Hadith 11:134
Waki’ narrated to us, Sufyan narrated to us, from Salim, from Sa’id ibn Jubayr, regarding the verse: "And do not think of those who have been killed in the way of Allah as dead; rather, they are alive with their Lord, receiving provision." He said: When Hamza ibn ‘Abd al-Muttalib and Mus’ab ibn ‘Umayr were struck down on the day of Uhud, they said, "Would that our brothers knew what good we have attained, so that they might increase in desire [for martyrdom]." Allah said, "I will inform them on your behalf." Then, "And do not think of those who have been killed in the way of Allah as dead; rather, they are alive with their Lord, receiving provision, rejoicing..." was revealed, up to His saying, "...the believers."
