Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: The angels did not fight alongside the Prophet (peace and blessings be upon him) except on the day of Badr; apart from that they came only as reinforcement. And the Prophet (peace and blessings be upon him) had only two horses with him: one belonged to Sayyiduna al-Miqdad bin al-Aswad (may Allah be pleased with him) and the other to Sayyiduna Abu Marthad al-Ghanawi (may Allah be pleased with him).
