It is reported on the authority of Ibrāhīm b. Al-Ash’ath that he said, “I asked Al-Fudayl b. ‘Ayyād – Allāh have mercy on him – about patience (al-sabr) in the face of adversity and he said, ‘It is to not broadcast it.’ I asked him about asceticism (al-zuhd) and he said, ‘Al-zuhd is to be content with what you have, and that is what it means to be rich.’ I asked him about prudence (al-wara’) and he said, ‘It is to stay away from what is forbidden.’ And I asked him about humbleness (al-tawādu’) and he said, ‘It is when you submit to the truth and comply no matter who you hear it from; even if it was from the most ignorant of people, you would be required to accept it from him.’”
