The Book of Prayers (Kitab Al-Salat)

Muslim :: Book 4 : Hadith 1727

Abu Musa al-Ash'ari reported Allah's Apostle (may peace be upon him) as saying: Keep refreshing your knowledge of the Qur'an, for I swear by Him in Whose Hand is the life of Mahammad that it is more liable to escape than camels which are hobbled.
