29:11
وَلَيَعْلَمَنَّ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ وَلَيَعْلَمَنَّ ٱلْمُنَـٰفِقِينَ
walayaʿlamanna l-lahu alladhīna āmanū walayaʿlamanna l-munāfiqīna
God will be sure to mark out which ones are the believers, and which the hypocrites.
Verily, Allâh knows those who believe, and verily, He knows the hypocrites [i.e. Allâh will test the people with good and hard days to discriminate the good from the wicked, although Allâh knows all that before putting them to test].
