Hadith 4:298

Narrated Anas bin Malik:

Allah's Apostle delivered a sermon and said, "Zaid received the flag and was martyred, then Ja'far took it and was martyred, then 'Abdullah bin Rawaha took it and was martyred, and then Khalid bin Al-Walid took it without being appointed, and Allah gave him victory." The Prophet added, "I am not pleased (or they will not be pleased) that they should remain (alive) with us," while his eyes were shedding tears.
