Allah's Will

He grants His favour to whomever He wills.

2:90Evil is that for which they sell their souls: that they should disbelieve in that which Allah hath revealed, grudging that Allah should reveal of His bounty unto whom He will of His slaves. They have incurred anger upon anger. For disbelievers is a shameful doom.

14:11Their messengers said unto them: We are but mortals like you, but Allah giveth grace unto whom He will of His slaves. It is not ours to bring you a warrant unless by the permission of Allah. In Allah let believers put their trust!

24:38That Allah may reward them with the best of what they did, and increase reward for them of His bounty. Allah giveth blessings without stint to whom He will.
