It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the angels fought alongside the Prophet (peace and blessings be upon him) only on the day of Badr; apart from that (in other battles) they came merely as help and reinforcement. And the Prophet (peace and blessings be upon him) had only two horses with him (at Badr): one belonging 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).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Ata' except Ayyub bin Thabit, and no one narrated it from Ayyub except Abd al-Aziz, and Ibrahim bin al-Mundhir is alone in narrating it."
