Qabisah bin Jabir al-Asadi (may Allah have mercy on him) narrates: The Commander of the Believers, Sayyiduna Umar bin al-Khattab (may Allah be pleased with him), wrote to Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him): "I want to divide the Sawad of Kufah among the Muslims who have prevailed (over it)." Sayyiduna Sa'd (may Allah be pleased with him) wrote back to him: "O Commander of the Believers, we have prevailed over a people who are the softest-hearted of Allah's creation, the most generous, the most blessed and the most open-handed; their hands give food and on their tongues is (the greeting of) peace. So, O Commander of the Believers, if you see fit, do not scatter them and do not divide (the land), and do not turn us away from the purpose for which Allah granted us victory, for the Messenger of Allah (peace and blessings be upon him) used to say: 'The honour of the Arabs lies in the tips of their spears and the hooves of their horses.'"
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Abd al-Malik except Salih, and Abdullah bin Umar bin Aban is alone in narrating it."
