In Chapter 6, verse 12, God repeats his law of Grace and Mercy for mankind again. The literal meaning of the words is: God has written upon Himself (has made obligatory on Him).

Again in Chapter 7, verse 156 God repeats “His law of Mercy and Grace” in the following words:
“With My chastisement do I afflict whom I will – but My grace overspreads everything: and so I shall confer it on those who are conscious of Me and spend in charity and who believe in Our messages.”

In an authentic tradition of the prophet, God says of Himself: “Verily, My Grace and Mercy outstrips My wrath.”


Allah swt is the best judge of whom is deserving of what.. and it is certainly a concept beyond our scope....
mercy that is given this world is 1% of that which he has willed upon himself on the day of judgement.. (if I am wrong on this someone more knowledgeable pls correct me)
