English translation
519. 'Urwah bin Az-Zubair narrated from a woman of the tribe of Banū An-Najjār that she said: "My house was one of the tallest houses around the Masjid, so Bilāl would call the Fajr Adhān from on top of it. He would come in the late night, before dawn broke, and would sit on the house, watching for dawn (to appear). When he would see it, he would stretch (his body) and say: 'O Allāh! I thank you, and seek Your help for the Quraish, that they may establish Your religion.' Then he would proclaim the Adhān." She said: "By Allāh! I don't remember that he left these phrases even one night!". (Hasan)
