Abū Bakr ibn al-Naḍr ibn Abī al-Naḍr narrated to us: Ḥajjāj ibn Muḥammad narrated to us; he said: Ibn Jurayj said: Nāfiʿ informed us, from Ibn ʿUmar, who said: When the Muslims first arrived in Madinah, they would gather and estimate the times for prayer, but no one called them to it. One day they discussed this. Some said, “Use a bell like the Christians’ bell.” Others said, “Use a horn like the Jews’ horn.” ʿUmar ibn al-Khaṭṭāb said, “Why not send a man to call people to prayer?” The Messenger of Allah (ﷺ) then said, “Bilāl, get up and call people to prayer.” Abū ʿĪsā said: This hadith from Ibn ʿUmar is hasan sahih gharīb.
