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 water will be whiter than milk and sweeter than honey, and there will be birds in it with necks like those of camels. Hazrat Umar (may Allah be pleased with him) submitted, "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, "O Umar! Those who eat them will be even healthier than them."
