Urwah ibn az-Zubayr reported on the authority of a woman from Banu an-Najjar. She said: My house was the loftiest of all the houses around the mosque (of the Prophet at Medina). Bilal used to make a call to the morning prayer from it. He would come there before the break of dawn and wait for it. When he saw it, he would yawn and say: O Allah, I praise you and seek Your assistance for the Quraysh so that they might establish Thine religion. He then would make the call to prayer. She (the narrator) said: By Allah, I do not know whether he ever left saying these words on any night. (Using translation from Abū Dāʾūd 519)   

كَانَ بَيْتِي مِنْ أَطْوَلِ بَيْتٍ حَوْلَ الْمَسْجِدِ فَكَانَ بِلَالٌ يُؤَذِّنُ عَلَيْهِ الْفَجْرَ فَيَأْتِي بِسَحَرٍ فَيَجْلِسُ عَلَى الْبَيْتِ ثُمَّ يَنْظُرُ إِلَى الْفَجْرِ فَإِذَا رَآهُ تَمَطَّى ثُمَّ قَالَ اللهُمَّ إِنِّي أَحْمَدُكَ وَأَسْتَعِينُكَ عَلَى قُرَيْشٍ أَنْ يُقِيمُوا دِينَكَ قَالَتْ ثُمَّ يُؤَذِّنُ قَالَتْ وَاللهُ مَا عَلِمْتُهُ كَانَ تَرَكَهَا لَيْلَةً وَاحِدَةً هَذِهِ الْكَلِمَاتِ  

[Machine] Khalid ibn Amr narrated to me and this is a rejected narration, not heard from anyone other than Khalid ibn Amr, and he is a weak narrator of rejected narrations.  

ثنا خَالِدُ بْنُ عَمْرٍو فَذَكَرَهُ وَهَذَا حَدِيثٌ مُنْكَرٌ لَمْ يَرْوِهِ غَيْرُ خَالِدِ بْنِ عَمْرٍو وَهُوَ ضَعِيفٌ مُنْكَرُ الْحَدِيثِ
