Sayyiduna Anas bin Malik (may Allah be pleased with him) said that a tailor invited the Prophet (peace and blessings be upon him) to a meal. Sayyiduna Anas (may Allah be pleased with him) said: I also went with the Messenger of Allah (peace and blessings be upon him) to eat, and barley bread and a broth containing gourd and pieces of dried meat were placed before the Messenger of Allah (peace and blessings be upon him). Sayyiduna Anas (may Allah be pleased with him) said: I saw the Messenger of Allah (peace and blessings be upon him) searching for the gourd around the sides of the dish. Since that day I too have loved gourd.
