It is narrated from Hazrat Anas (may Allah be pleased with him) that a person asked the Prophet (peace and blessings be upon him) about "Kawthar." The Prophet (peace and blessings be upon him) said that it is the name of a river which my Lord has granted me. Its soil is musk, its water is whiter than milk and sweeter than honey, and in it there will be birds with necks like camels. Hazrat Abu Bakr (may Allah be pleased with him) said, "O Messenger of Allah (peace and blessings be upon him)! Then those birds will be very healthy." The Prophet (peace and blessings be upon him) said, "Those who eat them will be even healthier than them."
