‘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."
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.”*
Narrated ‘Abd ar-Rahman b. ‘A’ish reported God’s Messenger as saying:
I saw my Lord in the most beautiful form, and He said, "What do the angels near My presence dispute about?" I replied," Thou knowest best.” Then He placed the palm of His hand between my shoulder-blades and I felt the coolness of it between my nipples! Then I knew what was in the heavens and the earth. And he recited, "Thus did We show Abraham the kingdom of the heavens and the earth, and it was so that he might have certainty (Al-Qur’an; 6:75).’’
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.
