Musannaf Ibn Abi Shayba 11:29

Shababa narrated to us, from Ibn Abi Dhi'b, from Sa'id bin Khalid, from Isma'il, from 'Abd al-Rahman bin Abi Dhi'b, from 'Ata' bin Yasar, from Ibn 'Abbas, that the Prophet, peace and blessings of Allah be upon him, came out to them while they were sitting. He said, "Shall I not inform you of the best of people in status?" We said, "Yes, O Messenger of Allah." He said, "A man holding the rein of his horse in the way of Allah until he is killed or dies." He said, "Shall I not inform you of the one who follows him?" They said, "Yes, O Messenger of Allah." He said, "A man secluded in a mountain pass, establishing prayer and giving zakat, keeping away from the evil of people."
