التوبة — At-Taubah Ayat 43
عَفَا اللّٰهُ عَنْكَۚ لِمَ اَذِنْتَ لَهُمْ حَتّٰى يَتَبَيَّنَ لَكَ الَّذِيْنَ صَدَقُوْا وَتَعْلَمَ الْكٰذِبِيْنَ
‘Afallāhu ‘ank(a), lima ażinta lahum ḥattā yatabayyana lakal-lażīna ṣadaqū wa ta‘lamal-kāżibīn(a).
"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."
