وعن جابر رضي الله عنه
قال: قال رجل: أين أنا يا رسول الله إن قتلت؟ قال: «في الجنة «فألقى تمرات كن في يده ثم قاتل حتى قتل»
A man asked the Messenger of Allah (sallallahu alayhi wa sallam): “Tell me where I will be if I am killed while fighting in the way of Allah?” He (sallallahu alayhi wa sallam) replied, “In Jannah.” The man threw away the few dates which he had in his hand, jumped into the battlefield and fought on till he was killed.
