Mishkat al-Masabih 4 Prayer كتاب الصلاة 811

وَعَنْ عَمْرِو بْنِ حُرَيْثٍ: أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَطَبَ وَعَلَيْهِ عِمَامَةٌ سَوْدَاءُ قَدْ أَرْخَى طَرَفَيْهَا بَيْنَ كَتِفَيْهِ يَوْمَ الْجُمُعَةِ. رَوَاهُ مُسلم

‘Amr b. Huraith said the Prophet preached on Friday wearing a black turban the ends of which he let hang between his shoulders. Muslim transmitted it.
