Hadith 2.2
Jihad
Musa b. ‘Ubaida, client of Muhammad b. al-Qasim, told that Muhammad b. al-Qasim sent him to al-Bara’ b. ‘Azib to ask him about God’s Messenger’s standard, and he said it was black and square, being made of a woollen rug. Ahmad, Tirmidhi and Abu Dawud transmitted it.
وَعَنْ مُوسَى بْنِ عُبَيْدَةَ مَوْلَى مُحَمَّدِ بْنِ الْقَاسِمِ قَالَ: بَعَثَنِي مُحَمَّدُ بْنُ الْقَاسِمِ إِلَى الْبَرَاءِ بْنِ عَازِبٍ يَسْأَلُهُ عَنْ رَايَةِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَقَالَ: كَانَتْ سَوْدَاءَ مُرَبَّعَةً مِنْ نَمِرَةٍ. رَوَاهُ أَحْمَدُ وَالتِّرْمِذِيُّ وَأَبُو دَاوُد
