حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، حَدَّثَنَا يَحْيَى بْنُ إِسْحَاقَ، وَهُوَ السَّالِحَانِيُّ حَدَّثَنَا يَزِيدُ بْنُ حَيَّانَ، قَالَ سَمِعْتُ أَبَا مِجْلَزٍ، لاَحِقَ بْنَ حُمَيْدٍ يُحَدِّثُ عَنِ ابْنِ عَبَّاسٍ، قَالَ كَانَتْ رَايَةُ رَسُولِ اللَّهِ صلى الله عليه وسلم سَوْدَاءَ وَلِوَاؤُهُ أَبْيَضَ . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ مِنْ هَذَا الْوَجْهِ مِنْ حَدِيثِ ابْنِ عَبَّاسٍ .

Muhammad ibn Rafi reported to us from Yahya ibn Ishaq—al-Salahani—from Yazid ibn Hayyan, who said: I heard Abu Mijlaz, Lahiq ibn Humayd, narrate from Ibn Abbas, who said: The banner (rayah) of the Messenger of Allah was black, and his standard (liwa) was white.
Abu Isa said: This hadith is hasan gharib through this chain, from Ibn Abbas.
Notes and open questions — unreviewed
The Arabic uses two distinct terms for the flags: rayah and liwa; the English witness renders them as flag and standard.
