The practice of I`tikaf in the mosque has certain etiquettes, which the Prophet (peace and blessings of Allah be upon him) taught his Ummah through both his words and actions.This Hadith illustrates some of those etiquettes. `A’ishah (may Allah be pleased with her) said: “The Messenger of Allah (peace and blessings of Allah be upon him), when in I`tikaf” which refers to remaining in the mosque for a specified period as an act of devotion “would lean his head toward me and I would comb his hair.” This means that he would draw his head close to `A’ishah (may Allah be pleased with her), and she would groom his hair without him entering the house. Her room was adjacent to the mosque. She added: “He would not enter the house except for a human necessity,” meaning that during his I`tikaf, he would only leave the mosque for essential needs such as relieving himself by going to the toilet..
