He is Allah, Ash-Shakoor (the One Most Ready to Appreciate and Reward Abundantly)…&"Indeed, Allah is Appreciative and Knowing&" (Al-Baqarah: 158)., &"Indeed, our Lord is Forgiving and Appreciative&" (Fâtir: 34).
He is Grateful when He receives just a small amount of good deeds from His slaves, and in return He forgives a great deal of bad deeds. For the sincere, he multiplies their good deeds without limit.
He grants those who thank Him and favours those who ask Him. He mentions those who mention Him; to the thankful He gives more, but for the Kafer there is loss. Allah the Exalted says: &"&"If you are grateful, I shall surely increase you (in favour); but if you deny, indeed, My Punishment is severe&" (Ibrahîm: 7).
