Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: "Indeed, there are some people who sit in the mosque, and the angels become their companions. If they are absent, the angels search for them; if they fall ill, the angels visit them; and if they have a need, the angels assist them. The one who sits in the mosque certainly attains at least one benefit: either someone benefits from him, or he speaks a word of wisdom, or he is waiting for mercy."
