Sayyiduna Ruwayfi' bin Thabit al-Ansari (may Allah be pleased with him) related that the Prophet (peace and blessings be upon him) said on the day of Hunayn: "Whoever believes in Allah and the Last Day must not give his water to another man's child; whoever believes in Allah and the Last Day must not take any animal from the spoils, (for) if he takes it and wears it out, he will still have to return it to the spoils; and whoever believes in Allah and the Last Day must not wear any garment from the spoils, (for) if he takes it and wears it threadbare, he will have to return it to the spoils."
