Mukhtasar Bukhari

‘Sayyiduna Mu’adh (may Allah be pleased with him) says that I was riding behind the Prophet (peace and blessings of Allah be upon him) on a donkey, whose name was ‘Ufair. The Prophet (peace be upon him) said: “O Mu’adh! Do you know what Allah’s right is upon His servants?” ... and the entire hadith was narrated which has already passed. (See the Book: Statement of Knowledge... Chapter: Disliking that people may not understand, for the one who leaves one group for another to teach them knowledge.)
