Sunan Abi Dawud
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى الرَّازِيُّ، أَخْبَرَنَا ابْنُ أَبِي زَائِدَةَ، أَخْبَرَنَا أَبُو يَعْقُوبَ الثَّقَفِيُّ، حَدَّثَنِي يُونُسُ بْنُ عُبَيْدٍ، - رَجُلٌ مِنْ ثَقِيفٍ مَوْلَى مُحَمَّدِ بْنِ الْقَاسِمِ - قَالَ بَعَثَنِي مُحَمَّدُ بْنُ الْقَاسِمِ إِلَى الْبَرَاءِ بْنِ عَازِبٍ يَسْأَلُهُ عَنْ رَايَةِ، رَسُولِ اللَّهِ صلى الله عليه وسلم مَا كَانَتْ فَقَالَ كَانَتْ سَوْدَاءَ مُرَبَّعَةً مِنْ نَمِرَةٍ .
Narrated Al-Bara' ibn Azib: Yunus ibn Ubayd, client of Muhammad ibn al-Qasim, said that Muhammad ibn al-Qasim sent to al-Bara' ibn Azib to ask him about the standard of the Messenger of Allah (ﷺ). He said: It was black and square, being made of a woollen rug.
