699 - Ahmad ibn Abi Surayj al-Razi narrated to us, Abu Ahmad al-Zubayri narrated to us, Masarrat ibn Ma'bad al-Lakhmi informed us — I met him in Kufa — Abu 'Ubayd, the chamberlain of Sulayman, narrated to me, saying: I saw 'Ata' ibn Yazid al-Laythi standing in prayer, and I went to pass in front of him, but he turned me back. Then he said: Abu Sa'id al-Khudri narrated to me that the Messenger of Allah, peace and blessings be upon him, said: "Whoever among you is able to ensure that no one passes between him and his direction of prayer, let him do so."(1)

700 - Musa ibn Isma'il narrated to us, Sulayman — meaning ibn al-Mughirah — narrated to us, from Humayd — meaning ibn Hilal — who said: Abu Salih said: I shall tell you of what I saw of Abu Sa'id and what I heard from him: Abu Sa'id entered upon Marwan and said: I heard the Messenger of Allah, peace and blessings be upon him, say: "When one of you prays toward something that screens him from the people, and someone wants to pass in front of him, let him push him in the chest. If he refuses, let him fight him, for he is only a devil."(2)
