Sunan Abi Dawud Book 15, Hadith 1
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.
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.”
Miqdan bin Shuraih reported on the authority of his father. I asked A’ishah about settling in the desert (to worship Allaah in loneliness). She said “The Apostle of Allaah(ﷺ) would go out (from Madina) to these torrential streams. Once he intended to go out to the desert (for worshipping Allaah). He sent me a She-Camel from the Camels of sadaqah that was not used as a mount. He said to me “A’ishah be lenient, for leniency makes a thing decorated and when it is removed from a thing it makes it defective.
