لِّيَسْـَٔلَ ٱلصَّـٰدِقِينَ عَن صِدْقِهِمْ ۚ وَأَعَدَّ لِلْكَـٰفِرِينَ عَذَابًا أَلِيمًا
Liyas'alas saadiqeena 'an sidqihim; wa a'adda lilkaa fireena 'azaaban aleemaa
God will question [even] the truthful about their sincerity, and for those who reject the truth He has prepared a painful torment.
so that he may question the truthful about their truthfulness; and for those who deny, he has prepared a painful punishment.
