It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that they set out on a journey with the Noble Prophet (peace and blessings be upon him), and the people split into groups and camped at a place, one group with so-and-so, another group with so-and-so. I was in the group of Sayyiduna Abu Bakr (may Allah be pleased with him). There was also a Bedouin with us. We camped near the house of some villagers, among whom was a pregnant woman. The Bedouin said to this woman: "Would you like to give birth to a boy? If you give me a goat, a boy will be born in your house." So the woman gave him a goat, and the Bedouin spoke to her in rhymed phrases and slaughtered the goat. When the people sat down to eat, a man said: "Do you know what kind of goat this is?" Then he told them the real story behind it. I saw Sayyiduna Abu Bakr (may Allah be pleased with him) forcing himself to vomit in order to express his aversion to that food.

Brief Explanation
Benefits: … Sayyiduna Abu Bakr as-Siddiq radi Allahu anhu did not realize it while eating, but when he came to know, he wished that not a single part of this unlawful thing should remain in his stomach; therefore, he deliberately began to induce vomiting.
