ثُمَّ نُنَجِّي رُسُلَنَا وَٱلَّذِينَ ءَامَنُواْۚ كَذَٰلِكَ حَقًّا عَلَيۡنَا نُنجِ ٱلۡمُؤۡمِنِينَ١٠٣

thumma nunajjī rusulanā wa-alladhīna āmanū kadhālika ḥaqqan ʿalaynā nunji l-mu'minīna

Then We will save Our messengers and those who have believed. Thus, it is an obligation upon Us that We save the believers.
