Just as the impact of Tawheed and Iman is evident in the Mu&"men&"s heart and the behavior concerned with only the self, it also reflects in his behaviour and manners with the people. The Prophet (peace be upon him) said: &"I have been sent to achieve the culmination of high moral standards&" (Narrated by al-Baihaqi).
Moreover, the Prophet made a connection between Iman and manners. He (peace be upon him) said: &"Among the believers who show the most perfect faith are those who have the best manners and are kindest to their families&" (Narrated by at-Tirmidthi).
The Mu&"men who has Tawheed is the one who understands that Allah always sees us, and the one who shows mercy to the people around him in different situations. Some of them are:
1-Dealing with parents: A Mu&"men who has Tawheed gives his parents their rights in the best way possible, for Allah has mentioned the parents along with Himself in the Qur’an. Allah says: 23- Your Lord has decreed that you not worship except Him, and to parents good treatment. Whether one or both of them reach old age (while) with you, say not to them (so much as): &"uff’, and do not repel them but speak to them a noble word. 24- Lower to them the wing of humility out of mercy and say: &"My Lord, have mercy upon them as they brought me up (when I was) small.&" 25- Your Lord is most knowing of what is within yourselves. If you should be righteous (in intention) - then indeed He is ever, to the often returning (to Him), Forgiving (Al-Isrâ&": 23-25).
Allah the Exalted says: &"We have enjoined upon man goodness to parents, but if they endeavour to make you associate with Me that of which you have no knowledge, do not obey them. To Me is your return, and I shall inform you about what you used to do&" (Al-&"Ankabût: 8).
2-Dealing with children: Though children are the adornments of this worldly life, as Allah says the following about them: &"Wealth and children are (but) adornment of the worldly life&" (Al-Kahf: 46),the Tawheed in the heart of a Mu&"men motivates him to bring up his children teaching them the correct manners of Islam, since Allah calls on the Mu&"meneen to protect themselves and their family from the fire of Jahannam (Hell). Allah says: &"O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones, over which are (appointed) angels, harsh and severe; they do not disobey Allah in what He commands them, but do what they are commanded&" (At-Tahrîm: 6).
He made this an obligation on every guardian. The Prophet (peace be upon him) said: &"Every one of you is a guardian, and is responsible for what is in his custody. The ruler is a guardian of his subjects and responsible for them; a husband is a guardian of his family and is responsible for it; a lady is a guardian of her husband&"s house and is responsible for it, and a servant is a guardian of his master&"s property and is responsible for it&" (Narrated by al-Bukhari).
3-Dealing with the wife: A Mu&"men who has Tawheed gives his wife her rights and treats her in the best way possible, as he fears Allah and is aware that He is watching him. Allah the Exalted says: &"Due to the wives is similar to what is expected of them, according to what is reasonable&" (Al-Baqarah: 228).
And the Prophet (peace be upon him) said: &"The best of you is the one who is best to his wife, and I am the best of you to my wives&" (Narrated by at-Tirmidthi).
When a women came to the Prophet (peace be upon him) complaining to him, he said: &"The best of you are those who are best to their womenfolk&" (Narrated by ibn Majah).
4-Dealing with the husband: Tawheed yields the fruits of feeling reverence towards Allah in the heart of the wife who is a Mu’men, and this causes her to give her husband all his rights as best as she can in order to attain Jannah. The Prophet (peace be upon him) said: “When a woman is punctual in (performing) her five daily Salah, fasts for the month of Ramadan, safeguards her chastity and obeys her husband, it will be said to her (on the day of Judgment): Enter Paradise through whichever door you wish” (Narrated by Ahmad).
Allah the Exalted ordered her not to ask him for what is more than he can fairly afford. Allah says: &"Let a man of wealth spend from his wealth, and he whose provision is restricted - let him spend from what Allah has given him. Allah does not charge a soul except (according to) what He has given it. Allah will bring about, after hardship, ease&" (At-Talâq: 7).
She is also not to ask him for divorce unless she has a plausible reason. The Prophet (peace be upon him) said: &"If any woman asks her husband for divorce without some strong reason, the odour of Paradise will be forbidden to her&" (Narrated by Ahmad).
Family ties and the neighbours&" rights: Allah has interlinked worship, Tawheed and a Mu&"men&"s treatment of his family, relatives and neighbours. Allah says: &"Worship Allah and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbor, the neighbor farther away, the companion at your side, the traveler, and those whom your right hands possess. Indeed, Allah does not like those who are self-deluding and boastful&" (An-Nisâ&": 36).
Allah the Exalted also says: &"So give the relative his right, as well as the needy and the traveler. That is best for those who desire the countenance of Allah, and it is they who will be the successful&" (Ar-Rûm: 38).
And the Prophet (peace be upon him) said: &"He who believes in Allah and the Last Day should do good to his neighbour&" (Narrated by Muslim).
Iman bears fruits of good manners in the heart of the Mu’men who has Tawheed. A Mu&"men always gives good advice to the people around him and is sincere in dealing with them. These are some of the best deeds which a Mu&"men can perform to draw closer to Allah the Exalted:
1-Good manners: Allah says the following while describing His Prophet (peace be upon him): &"Indeed, you are of a great moral character&" (Al-Qalam: 4).
And the Prophet (peace be upon him) said: “The fear of Allah and good morals are the two major characteristics which lead to Paradise” (Narrated by at-Termidthi).
The Prophet (peace be upon him) also said: “The most beloved of people according to Allah is he who brings most benefit, and the most beloved of deeds according to Allah the Mighty, the Magnificent, is that you bring happiness to a fellow Muslim, or relieve him of distress, or pay off his debt, or stave away hunger from him. It is more beloved to me that I walk with my brother Muslim in his time of need than I stay secluded in the mosque (I&"tikaf) for a month” (Narrated by at-Tabarani).
2-Truthfulness: Allah says: &"O you who have believed, fear Allah and be with those who are true&" (At-Taubah: 119).It is foolishness to think that the Prophet (peace be upon him) (cheated his nation by not telling them all that Allah told him, and not advising them about what they need so he) taught his Ummah only about istinja (purifying oneself after defecating) and did not teach them Tawheed. In fact Tawheed was described by the Prophet in his saying: &"I have been commanded to fight against people so long as they do not declare that there is no god but Allah (i.e have Tawheed)…&" (Narrated by Bukhari) – indicating that whatever is protected by Tawheed of wealth and blood is (the result of the actualization of) the true meaning of Tawheed.
And the Prophet (peace be upon him) said: &"Truthfulness leads to righteousness, and righteousness leads to Paradise; and a man keeps on telling the truth until he becomes a truthful person. Falsehood leads to Al-Fajoor (i.e. wickedness, doing evil), and Al-Fajoor (wickedness) leads to the (Hell) Fire, and a man may keep on telling lies until he is written before Allah as a liar&" (Narrated by al-Bukhari).
The Prophet (peace be upon him) also said: “There are three signs of a hypocrite: when he speaks, he tells lies; when he makes a promise, he breaks it; and when he is entrusted, he betrays his trust” (Narrated by al-Bukhari).
3-Giving advice and not cheating: The Prophet (peace be upon him) said, &"Allah does not entrust to his bondsman the responsibility of managing the affairs of his subjects and he dies as a dishonest (ruler), but Paradise is forbidden by Allah for such (a ruler)&" (Narrated by Muslim).
The Messenger of Allah (peace be upon him) happened to pass by a heap of food (corn). He thrust his hand in that (heap) and his fingers became moistened. So he said to the owner of the heap of food (corn): “What is this?” He replied: “O Messenger of Allah, these have been drenched by rainfall.” The Prophet remarked: “Why did you not place this (the drenched part of the heap) on top of the other food so that the people could see it? He who deceives is not of me (i.e. is not one who follows his guidance)&" (Narrated by Muslim).
