The Prophet ﷺ used to strive hard in worship to draw closer to Allah, Exalted is He, all the time, and one such time was the last ten days of Ramadan when he ﷺ used to observe I’tikaaf (i.e., a spiritual retreat in the mosque to devote oneself exclusively to worship), to dedicate himself exclusively to observing fasting, performing prayer, reciting Dhikr (remembrance of Allah), and other worshipful acts, and to seek the Night of Al-Qadr. In this hadeeth, the Mother of the Believers, ‘Aa’ishah (may Allah be pleased with her) used to observe I‘tikaaf in the last ten nights of Ramadan, starting from the 21st night till the end of the month. I‘tikaaf means a spiritual retreat in the mosque to draw closer to Allah, Exalted is He, (by devoting oneself exclusively to worship). The Prophet ﷺ used to observe I‘tikaaf during the last ten nights of Ramadan and did not neglect it until he died. After his death, his wives (may Allah be pleased with them) used to observe I‘tikaaf at the mosque in the last ten days of Ramadan. It was narrated in Saheeh Al-Bukhaaree on the authority of ‘Aa’ishah (may Allah be pleased with her) that the Prophet ﷺ used to observe I‘tikaaf along with some of his wives. They used to observe I‘tikaaf during his lifetime and after his death. At first, the Prophet ﷺ used to observe I‘tikaaf in the first ten nights of Ramadan, and later on observed it in the middle ten nights of Ramadan. Near the end of his life, he ﷺ observed I‘tikaaf in the last ten nights of Ramadan, seeking the Night of the Qadr. It is deduced from the hadeeth that it is allowable for women to observe I‘tikaaf at the mosque provided that the due requirements set by the Laws of Islam are met..
