It was narrated in the hadeeth of ‘Aa’ishah (may Allaah be pleased with her) that the Prophet (peace and blessings of Allaah be upon him) used to spend the last ten days of Ramadaan in i’tikaaf until he passed away, then his wives observed i’tikaaf after him.” Narrated by al-Bukhaari, 1922; Muslim, 1172.

Women cal also do i’tikaaf it easy for women comparitively, and i’tikaaf can be of small durations as well, i.e from asar to magrib or magrib to isha etc u just have to do proper niyat and avoid talking in that time and indulge yourself in ibadah
