﴿ وَلَئِن مُّتُّمْ أَوْ قُتِلْتُمْ لَإِلَى ٱللَّهِ تُحْشَرُونَ ﴾

“for, indeed, if you die or are slain, it will surely be unto God that you shall be gathered.”

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.
