Al- Adab Al- Mufrad by Al-Bukhari

415. Salim ibn 'Abdullah reported from his father that 'Umar used to say to his sons, "Separate in the morning and do not meet together in the same house. I fear that you might split up or that some evil may take place between you."

416. Ibn 'Umar saw a shepherd with some sheep in a bad place and saw a place which was better than it. He told him, "Woe to you, shepherd! Move them! I heard the Messenger of Allah, may Allah bless him and grant him peace, say, 'Every shepherd is responsible for his flock.'"

417. Ibn 'Abbas reported that the Prophet, may Allah bless him and grant him peace, said, "We do not give a bad example. The one who takes back his gift is like the dog who returns to his own vomit."

418. Abu Hurayra reported that the Messenger of Allah, may Allah bless him and grant him peace, said, "The believer is guileless and generous while the corrupt is a swindler and miserly."
