Abu Sa'id al-Khudri reported God’s Messenger as saying, “When you see a man frequenting the mosque, testify that he has faith, for God says, ‘God’s mosques are visited only by those who believe in God and the last day.”*
Buraida reported God's Messenger as saying, “Announce to those who make a practice of walking to mosques during the times of darkness the good news that they will have complete light on the day of resurrection.
Tirmidhi and Abu Dawud transmitted it, and Ibn Majah transmitted it from Sahl b. Sa'd and Anas.
‘Uthman b. Mazun said, “Messenger of God, grant us permission to become eunuchs." God’s Messenger replied, “He who makes another a eunuch or becomes one himself does not belong to us; fasting serves that purpose among my people." He then said, "Grant us permission to lead the wandering life of the devotee." He replied, "The wandering life of the devotee among my people is jihad in God’s path." He said, "Grant us permission to adopt monkery.” He replied, "Monkery among my people consists of sitting in mosques waiting for the time of prayer."
He also reported God’s Messenger as saying, “The rewards of my people were placed before me, even and the sins of my people were placed before me, and I saw no sin greater than that a man should memorise a sura or verse of the Qur’an, then forget it."*
