What is forbidden for the one in i'tikaf to do

Question : The questioner says: Honorable Shaykh, what is forbidden for the one in i'tikaf to do?

Answer : The one in i'tikaf. He is only bound to the mosque for the worship of Allah (Mighty and Majestic), so he is upright in the mosque, far from the worldly life.
Based on this, it is not permissible for him to approach women, due to the saying of Allah (Blessed and Exalted is He): But he may hand things to his wife and speak with her, just as the Prophet (peace and blessings be upon him) used to stick his head out to Aisha (may Allah be pleased with her) while he was in i'tikaf, and she would comb his hair while he was in i'tikaf. It is not permissible for him to go out for buying and selling, nor is it permissible for him to go out for food and drink unless he cannot find someone to bring him his food and drink. It is not permissible for him to leave the mosque to perform wudu' or relieve himself if there is something in the mosque by which he can relieve himself and perform wudu', as in the mosques of cities that have bathrooms and toilets inside the mosque. And if he is required to perform ghusl due to janabah and there is nothing in the mosque with which he can perform ghusl, he may go out to his house, perform ghusl, and then return, because this is a need. In summary, the one in i'tikaf does not leave his place of i'tikaf except for something he absolutely needs, either physically or religiously. An example of what is physically necessary is food and drink if he cannot find someone to bring them. An example of what is religiously necessary is performing ghusl for janabah.
