Strengthening the Ummah

Allah's Messenger (ﷺ) forbade (1) the meeting of the caravan (of goods) on the way, (2) and that a residing
person buys for a bedouin, (3) and that a woman stipulates the divorce of the wife of the would-be
husband, (4) and that a man tries to cause the cancellation of a bargain concluded by another. He also
forbade An-Najsh (see Hadith 824) and that one withholds the milk in the udder of the animal so that
he may deceive people on selling it.
