Q: My husband wants to observe i?tikaf (ritual seclusion in the mosque) in Ramadan, Allah Almighty, willing. He will observe it in a masjid near our house. Is it valid that he comes home after finishing work and takes a bath and then goes to the masjid and repeats this process throughout the period of i?tikaf? He also comes home before he goes to work to change his clothes and take a bath. We want to know whether the conditions of the validity of i?tikaf include not entering the marital house?
