Quran 9:43 — Surah At-Tawbah, ayah 43

عَفَا ٱللَّهُ عَنكَ لِمَ أَذِنتَ لَهُمۡ حَتَّىٰ يَتَبَيَّنَ لَكَ ٱلَّذِينَ صَدَقُواْ وَتَعۡلَمَ ٱلۡكَٰذِبِينَ

May Allah pardon you, [O Muhammad]; why did you give them permission [to remain behind]? [You should not have] until it was evident to you who were truthful and you knew [who were] the liars

Neka ti Allah oprosti što si dozvolio da izostanu, dok se nisi uvjerio koji od njih govore istinu, a koji lažu.
