Nabi (s.a.w)'s I'tikaaf for the whole month

Answer

Hazrat Abu Saeed Al-Khudri (Radhiyallahu Anhu) Narrates that Rasulullah (Salallahu Alaihi Wasallam) would perform i’tikaaf of the first ten days of Ramadhan, then he would perform i’ttikaaf of the second ten days in a Turkish tent, then he would take his head out (of the tent) and say “I performed i’tikaaf of the first ten days looking for this night (lailat-ul-Qadr), then I performed i’tikaaf of the second ten nights, then someone came to me, so then I was told that it is in the last ten nights.......(Muslim)” (Mishkaat Shareef Vol 1 Page 182) It is mention in Bukhari Shareef as well (Chapter: Performing sajdah on mud). In this hadith it is proven that Nabi (s.a.w) performed i'tikaaf for the whole month in that particular year.
