It is narrated from Hazrat Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: In Paradise, there will be birds as large as the necks of camels, which will graze among the trees. 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, and Abu Bakr! I hope that you will be among those who eat them.
