abudawud:520[Chain 1] Mūsá b. Ismāʿīl > Qays / Ibn al-Rabīʿ [Chain 2] Muḥammad b. Sulaymān al-Anbārī > Wakīʿ > Sufyān > ʿAwn b. Abū Juḥayfah from his father

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.  

أبو داود:٥٢٠حَدَّثَنَا 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
