It is narrated from Yahya bin Saeed that the Messenger of Allah, peace and blessings be upon him, encouraged participation in jihad (on the day of Badr), and described the condition of Paradise. Meanwhile, an Ansari man (the same Sayyiduna Umair bin Humaam, may Allah be pleased with him) was eating dates he had in his hand. He said: I have great desire for the world; if I sit waiting to finish these dates, then he threw away the dates, picked up his sword, began to fight, and was martyred.
