(V.6:125) If Allâh تعالى wants to do good to a person, He makes him comprehend the religion [the understanding of the Qur’ân and the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم].
Narrated Mu‘âwiya رضي الله عنه in a Khuthah (religious talk): I heard Allâh’s Messenger صلى الله عليه وسلم saying, "If Allâh wants to do good to a person, He makes him comprehend the religion [the understanding of the Qur’ân and the Sunnah (legal ways) of the Prophet صلى الله عليه وسلم]. I am just a distributor, but the grant is from Allâh. (And remember) that this nation (true Muslims, real followers of Islâmic Monotheism) will remain obedient to Allâh’s Orders [i.e., following strictly Allâh’s Book (the Qur’ân) and the Prophet’s Sunnah (legal ways)] and they will not be harmed by anyone who will oppose them (going on a different path) till Allâh’s Order (Day of Judgement) is established." (Sahih Al-Bukhâri, Vol.1, Hadîth No.71).
