The ruling on I’tikaaf

It is Sunnah Mu’akkadah(confirmed Sunnah), an action which the Prophet, Peace andBlessings of Allah be upon him,  alwaysdid, and he made up some of it that he missed. ‘Azzaam said concerningthis: “Al-masnoon (the Sunnah) is that which the Muslim doesvoluntarily to draw closer to Allah, seeking to earn reward from Himand following the example of the Messenger of Allah, Peace andBlessings of Allah be upon him, . It was reported that he did thisand persisted in it.” (p.114).
