Abu Juhaifah reported:

I came to the prophet ﷺ at Mecca; he was sitting in a tent made of leather. Then Bilal came out and called to prayer. I looked at his mouth following him this side and that side (i.e., right and left). Later at his Messenger of Allah ﷺ came out clad in a red suit, i.e, wearing the sheets of the Yemen, of the Qatri design. The version narrated by Musa has the word; “I saw Bilal going towards al-Abtah”.

He then made a call to prayer. When he reached the words “ come to prayer, come to salvation”. He turned his neck right and left, respectively; he did not turn himself (with his whole body). He then entered (his house) and came out with a lancet. The narrator then reported the rest of the tradition.

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا قَيْسٌ يَعْنِي ابْنَ الرَّبِيعِ، ح وَحَدَّثَنَا مُحَمَّدُ بْنُ سُلَيْمَانَ الأَنْبَارِيُّ، حَدَّثَنَا وَكِيعٌ، عَنْ سُفْيَانَ، جَمِيعًا عَنْ عَوْنِ بْنِ أَبِي جُحَيْفَةَ، عَنْ أَبِيهِ، قَالَ أَتَيْتُ النَّبِيَّ ﷺ بِمَكَّةَ وَهُوَ فِي قُبَّةٍ حَمْرَاءَ مِنْ أَدَمٍ فَخَرَجَ بِلاَلٌ فَأَذَّنَ فَكُنْتُ أَتَتَبَّعُ فَمَهُ هَا هُنَا وَهَا هُنَا . قَالَ ثُمَّ خَرَجَ رَسُولُ اللَّهِ ﷺ وَعَلَيْهِ حُلَّةٌ حَمْرَاءُ بُرُودٌ يَمَانِيَةٌ قِطْرِيٌّ . وَقَالَ مُوسَى قَالَ رَأَيْتُ بِلاَلاً خَرَجَ إِلَى الأَبْطَحِ فَأَذَّنَ فَلَمَّا بَلَغَ حَىَّ عَلَى الصَّلاَةِ حَىَّ عَلَى الْفَلاَحِ . لَوَى عُنُقَهُ يَمِينًا وَشِمَالاً وَلَمْ يَسْتَدِرْ ثُمَّ دَخَلَ فَأَخْرَجَ الْعَنَزَةَ وَسَاقَ حَدِيثَهُ .
