Sunan Abi Dawud Book 14, Hadith 164
A’ishah(may Allaah be pleased with her) said “One of the wives of the Apostle of Allaah(ﷺ) observed I’tikaf along with him (in the mosque). She would see yellowness and redness. Sometimes we would place a washbasin while she prayed.”
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 Messenger of Allah (ﷺ) has set free. He said: This slave-girl too? He sent her along with them.
Abu Sa’id Al Khudri said “A Bedouin asked the Prophet (ﷺ) about emigration. He replied “Woe to you! The matter of emigration is severe. Have you a Camel? He said, Yes. He asked “Do you pay its zakat? He said, Yes. He said, Then work (anywhere) beyond the seas. Allaah will not reduce anything from (the reward of) your work.
