And whether you die or are killed, unto Allah you will 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.

وَلَئِنْ مُتُّمْ أَوْ قُتِلْتُمْ لَإِلَى اللَّهِ تُحْشَرُونَ  

{ولئن} لام قسم {مُتُّمْ} بالوجهين {أو قُتلتم} في الجهاد وغيره {لإلى الله} لا إلى غيره {تُحشرون} في الآخرة فيجازيكم.
