Do not hate praying in the presence of someone who does not pray, even if he is talking; for Nafi' said: "Ibn Umar used to say: If I do not find a way to a pillar of the mosque, he would say: Let me lean on your back." This is found in Musannaf Ibn Abi Shaybah 1: 250. See also: Majma' al-Anhar 1: 121.
