This was expressly forbidden by this Qur anic statement. That, however, does not include having a normal relationship with one s wife during Itikaf . One may go home to inquire if his family needs anything. During this brief visit, his wife may attend to his own needs, such as combing his hair. It is needless to say that Itikaf is not easy for everyone to observe.
People have to attend to their needs and continue their work.
It is possible to limit one s Itikaf to one night, or even a portion of one night. According to scholars, one may make his stay in a Mosque, a stay of Itikaf , at any time, if he dedicates his time to worship, and intends his stay for such dedication. It is needless to say that Itikaf is highly rewarded by Allah, as every action therein involves dedication.
