It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "The Messenger of Allah (peace and blessings be upon him) would neither raise the standing of a man of rank in his sight nor lower it, except on the basis of piety (taqwa)."
No one narrated these two hadiths from Urwah (may Allah have mercy on him) except Abu al-Aswad Muhammad bin Abd al-Rahman (may Allah have mercy on him), and no one from Abu al-Aswad (may Allah have mercy on him) except Ibn Lahi'ah (may Allah have mercy on him), and Mansur bin Ammar (may Allah have mercy on him) is alone in narrating both of them.
