Ruwaifi' b. Thabit reported the Prophet as saying, “He who believes in God and the last day must not ride a packhorse belonging to the booty of the Muslims and put it back when he has emaciated it; and he who believes in God and the last day must not wear a garment belonging to the booty of the Muslims and put it back when he has made it threadbare.”
Muhammad b. Abul Mujalid reported ‘Abdallah b. Abu Aufa as saying he asked whether they set aside the fifth of food in the time of God’s Messenger and received the reply that on the day of Khaibar they captured food and a man would come and take as much of it as he needed and then go away.
Khaula, daughter of Qais, told of hearing God’s Messenger say, “This property is fresh and sweet and he who gets it in a proper way will be blessed in it, but he who improperly acquires such property of God and His Messenger as his soul wishes will have nothing but hell on the day of resurrection.”
