أَخْبَرَنَا أَبُو الْوَلِيدِ الطَّيَالِسِيُّ ، وَعَفَّانُ ، قَالَا : حَدَّثَنَا شُعْبَةُ ، عَنْ خَالِدٍ الْحَذَّاءِ ، عَنْ أَبِي قِلَابَةَ ، عَنْ أَنَسٍ ، قَالَ :" أُمِرَ بِلَالٌ أَنْ يَشْفَعَ الْأَذَانَ وَيُوتِرَ الْإِقَامَةَ "

Abu Al-Walid Al-Tayalisi and Affan told us, saying: Shu’bah told us, on the authority of Khaled Al-Hadha’, on the authority of Abu Qalabah, on the authority of Anas, who said: “ Bilal was ordered to recite the call to prayer and recite the Iqamat Witr.”
