15 - Sa'id ibn Mansur narrated to us, saying: Ya'qub ibn 'Abd al-Rahman narrated to us, [84] from Abu Hazim, from Abu Salih al-Samman, from Abu Hurayrah, that the Messenger of Allah (may Allah bless him and grant him peace) said: "You must listen and obey, in your hardship and your ease, in what you like and what you dislike, and even when others are given preference over you."
