[Do you fear] lest someone be given [knowledge] like you were given or that they would [thereby] argue with you before your Lord?” Say, “Indeed, [all] bounty is in the hand of Allah – He grants it to whom He wills.

O you who have believed, whoever of you should revert from his religion – Allah will bring forth [in place of them] a people He will love and who will love Him [who are] humble toward the believers, powerful against the disbelievers; they strive in the cause of Allah and do not fear the blame of a critic. That is the favor of Allah; He bestows it upon whom He wills. And Allah is all-Encompassing and Knowing.  (Quran 5:54)
