6. Ali ibn Ibrahim has narrated from his father from al-Qasim ibn Muhammad from Sulayman ibn Dawud al-Minqari from Hafs ibn Ghiyath who has said that
abu ‘Abdallah (a.s.) said the following. “Whoever acquires knowledge and practice what he has learned and teach it to others for the sake of Allah, among the angels of heavens he will be called a great personality. It will be said there: ‘He learned for the sake of Allah, practiced for the sake of Allah and taught it for the sake of Allah.”
