And Abu al-Tahir narrated to me, saying: Abdullah ibn Wahb informed us, saying: Jarir ibn Hazim narrated to us that Ayyub narrated to him that Nafi' narrated to him that Abdullah ibn Umar narrated to him that Umar ibn al-Khattab asked the Messenger of Allah, peace and blessings be upon him, while he was at al-Ji'ranah after returning from al-Ta'if, saying: "O Messenger of Allah, I had vowed during the pre-Islamic period to observe i'tikaf for a day in the Sacred Mosque, so what do you think?" He said: "Go and observe i'tikaf for a day." He said: And the Messenger of Allah, peace and blessings be upon him, had given him a slave-girl from the khums (the fifth of the spoils). When the Messenger of Allah, peace and blessings be upon him, freed the captives of the people, Umar ibn al-Khattab heard their voices saying: "The Messenger of Allah, peace and blessings be upon him, has freed us." He said: "What is this?" They said: "The Messenger of Allah, peace and blessings be upon him, has freed the captives of the people." So Umar said: "O Abdullah, go to that slave-girl and set her free."
