Bismillah, Assalaam Alaykum Shaykh, Can a man put a condition in the marriage contract which stipulates his wife cannot marry after his death? Death such as on the battlefield or by other means? May Allaah reward you with good. Wa'salaam
All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
Allaah Knows best.
