«أخذ الراية زيد فأصيب ثم أخذها جعفر فأصيب ثم أخذها عبد الله بن رواحة فأصيب ثم أخذها خالد عن غير إمرة ففتح الله عليه وما يسرني أنهم عندنا - أو قال - وما يسرهم أنهم عندنا»
The Prophet (peace and blessings be upon him) said:
"Zayd took the banner and was martyred, then Ja'far took it and was martyred, then Abdullah bin Rawahah took it and he too was martyred. Then Khalid took it on his own without being appointed, and Allah granted victory at his hands. And it would not please me that they were with us" - or he said - "and it would not please them that they were with us."
