While the Prophet (ﷺ) was in the market, somebody, called, "O Abul-Qasim." The Prophet (ﷺ) turned to him. The man said, "I have called to this (i.e. another man)." The Prophet (ﷺ) said, "Name yourselves by my name but not by my Kunya (name)." (In Arabic world it is the custom to call the man as the father of his eldest son, e.g. Abul-Qasim.) (See Hadith No. 737, Vol. 4)
Sahih al-Bukhari Book 34, Hadith 73
← Previous Hadith Allah's Messenger (ﷺ) said, "The congregational prayer of anyone amongst you is more than twenty (five or twenty seven) times in reward than his prayer in the market or in his house, for if he performs ablution completely and then goes to the mosque with the sole intention of performing the prayer, and nothing urges him to proceed to the mosque except the prayer, then, on every step which he takes towards the mosque, he will be raised one degree or one of his sins will be forgiven. The angels will keep on asking Allah's forgiveness and blessings for everyone of you so long as he keeps sitting at his praying place. The angels will say, 'O Allah, bless him! O Allah, be merciful to him!' as long as he does not do Hadath or a thing which gives trouble to the other." The Prophet (ﷺ) further said, "One is regarded in prayer so long as one is waiting for the prayer."
