The kinds of birds and animals that exist in Paradise are known only to Allah. He ta’ala told us that among the delights enjoyed by the people of Paradise will be:

“..and the flesh of fowls any that they may desire” [56:21]

at-Tirmidhi reports from Anas that the Messenger of Allah (saw) was asked, “What is al-Kawthar?” He said, “That is a river that Allah has given me… and in it are birds with necks like the necks of camels”. ‘Umar said, These birds will be in bliss”. The Messenger of Allah (saw) said, “Those who eat them will be more blissful””. [Mishkaat al-Masaabeeh, 2/91]

al-Haakim and Abu Na’eem reported from Ibn Mas’oud that “a man brought a haltered she-camel and said, “O Messenger of Allah, this she-camel is for the sake of Allah”. He said, “You will have seven hundred haltered she-camels in Paradise” [Silsilat as-Saheehah, 2/228 no. 634; a similar report is narrated by Muslim, Mishkaat al-Masaabeeh, 2/350, 3799]
