2. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from Dawud ibn Sarhan who has said the following: “I was in al-Madinah in the month of Ramadan and I said to abu ‘Abd Allah , that I wanted to remain in ’ Ttikaf. What should I say and what should I place upon myself?’ He (the Imam) said, ‘You must not leave the Masjid except for something without which you cannot do; and you must not sit in the shadow until you return to your place.”

3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Hammad from al-Halabiy who has said the following: “Abu ‘Abd Allah , has said, ‘It is not proper for one who is in ’Ttikaf to leave the Masjid, unless it is for such a need without which he cannot do. He then must not sit in the shadow until he returns to his place, and must not go out for anything except a funeral or to visit a patient and must not sit until he returns. ’Ttikaf of woman is also under the same rules.’”
