وَلَئِن مُّتُّمْ أَوْ قُتِلْتُمْ لَإِلَى ٱللَّهِ تُحْشَرُونَ
And whether you die or are killed, unto Allāh you will be gathered.
Translation: Saheeh International
Tafsir
And if wa-la-in the lām is for oaths you die read in both ways muttum or mittum or are slain in the holy struggle or otherwise it is to God and to none other than Him that you shall be mustered in the Hereafter and He will requite you.
