What is permissible for the person making ‘Itikaaf:

[1]: It is permissible for him to leave the masjid in order to fulfill a need. And it is permissible for him to stick his head out of the masjid to have it washed and combed.

‘Aa’ishah RAA said: “And the Messenger of Allaah (sallallaahu alayhi wasallam) would enter his head in my presence while he was making ‘Itikaaf in the masjid, and I was in my apartment. So I would comb his hair, [and in one narration: I would wash it, even though there was the threshold between me and him, and I would be menstruating]. And he (sallallaahu alayhi wasallam) would not enter the house unless he had a [human] need, while making ‘Itikaaf.”

[2]: It is permissible for the one making ‘Itikaaf and others to make wudoo (ablution) in the masjid, based on the saying of a man who would serve the Prophet (sallallaahu alayhi wasallam): “The Prophet (sallallaahu alayhi wasallam) would make a light wudoo (ablution) in the masjid.”

[3]: He may set up a small tent in the back *of the masjid in which to make ‘Itikaaf. This is since ‘Aa’ishah RAA would set up a khibaa (tent) for the Prophet (sallallaahu alayhi wasallam) when he would make *‘Itikaaf. And this was from his (sallallaahu alayhi wasallam) command.

And one time he made ‘I’tikaaf in a small tent that had a mat covering its doorway.

May Allah accept it from you and us. Aameen
