Does the person in i'tikaf (spiritual retreat in the mosque) leave the mosque to cook food?

The questioner : And he is the questioner: Is it permissible for the muhtasib (market inspector) to stand to take the position from the bad one, and to leave also to request us?

The Shaykh : I believe the scholars (may Allah have mercy on them) held that it is permissible for the one in i'tikaf to leave for something that is necessary if no one brings it to him. So if a person is in i'tikaf and has no one to bring him food and drink, and he goes and prepares it, there is no blame on him for that. Or if he leaves the mosque to relieve himself, there is no blame on him for that. But the issue of cooking and preparing, I do not see it as permissible, because now there are many restaurants around the mosque. He can take a loaf of bread and a side dish, eat it, and then return quickly. As for staying in his house to cook, and to adjust and change things, no, that is not valid.
