عَنْ أَبِي قَتَادَةَ رَضِيَ اللَّهُ عَنْهُ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ خَيْرُ الْخَيْلِ الْأَدْهَمُ الْأَقْرَحُ الْأَرْثَمُ مُحَجَّلُ الثَّلَاثِ مُطْلَقُ الْيَمِينِ فَإِنْ لَمْ يَكُنْ أَدْهَمَ فَكُمَيْتٌ عَلَى هَذِهِ الشِّيَةِ
It is narrated from Sayyiduna Abu Qatadah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: The best horse is the one that is deep black, with a light whiteness on its forehead and whiteness on the upper lip, and three of its legs are white while the right leg is black. If a deep black horse is not available, then a reddish-black horse will suffice, but the rest of its characteristics should remain the same.
