It is narrated from Sayyiduna Abd al-Rahman bin Abi Aqil al-Thaqafi (may Allah be pleased with him) that he said: I came to the Messenger of Allah (peace and blessings be upon him) with the delegation of Banu Thaqif. We travelled along one of the roads of Madinah until we made our camels kneel at (his) door. At that time there was no one among the people more hateful to us than the man to whom we were going in (that is, at first we had intense hatred for him). But when we entered, greeted him and gave our pledge of allegiance, then by the time we came out there was no one among the people more beloved to us than the man from whose presence we had come out. I said: O Messenger of Allah! Did you not ask your Lord for a kingdom like the kingdom of Sulayman (peace be upon him)? He (peace and blessings be upon him) smiled and said: "Perhaps your companion (the Prophet, peace and blessings be upon him) has with Allah something better than the kingdom of Sulayman (peace be upon him). Allah gave every prophet one supplication (which was to be accepted). Some of them asked for worldly things with it and were given them, and some prayed against their people and they were destroyed. Allah gave me a supplication too, and I have kept it hidden (in reserve) with my Lord as intercession for my Ummah on the Day of Resurrection." Muslim used Ali bin Hashim as evidence, and Abd al-Rahman bin Abi Aqil al-Thaqafi is a Companion whom our imams have used as evidence in their Musnad collections. As for Abd al-Jabbar bin al-Abbas, he is one of those narrators whose hadiths are collected, and his Musnad narrations are counted among the Kufans.
