Sura 9 At-Tawbah (The Repentance), vers 43

1. عَفَا اللَّهُ عَنْكَ لِمَ أَذِنْتَ لَهُمْ حَتَّىٰ يَتَبَيَّنَ لَكَ الَّذِينَ صَدَقُوا وَتَعْلَمَ الْكَاذِبِينَ

   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.

   9:43
