وَلَيَعْلَمَنَّ اللَّهُ الَّذِينَ آمَنُوا وَلَيَعْلَمَنَّ الْمُنَافِقِينَ (11)
(29:11) Allah will surely ascertain who are the believers and who are the hypocrites. *16
*16) That is, "Allah provides occasions for the trial again and again so that the faith of the believers and the hypocrisy of the hypocrites become manifest, and whatever is hidden in the hearts becomes exposed. The same thing has been said in Al-i-`Imran: 179: "Allah will not leave the believers in the state in which you happen to be at present: He will surely separate the pure from the impure people."
