Narated By Abdullah ibn Umar : The tradition mentioned above (No. 2468) has also been transmitted by Abdullah ibn Budayl through a different chain of narrators in a similar way.
This version adds: While he (Umar) was observing i’tikaf (in the sacred mosque), the people uttered (loudly): “Allah is most great.” He said: What is this, Abdullah? He said: These are the captives of the Hawazin whom the Apostle of Allah (PBUH) has set free. He said: This slave-girl too? He sent her along with them.
