[22].Surah Al-Hajj [The Pilgrimage]: Ayat 30

Ayat 30. That (Manâsik prescribed duties of Hajj is the obligation that mankind owes to Allah), and whoever honours the sacred things of Allah, then that is better for him with his Lord. The cattle are lawful to you, except those (that will be) mentioned to you (as exceptions). So shun the abomination (worshipping) of idol, and shun lying speech (false statements)

[Tafseer] Such (is the Pilgrimage): whoever honours the sacred rites of Allah, for him it is good in the Sight of his Lord. Lawful to you (for food in Pilgrimage) are cattle, except those mentioned to you (as exception): but shun the abomination of idols, and shun the word that is false. The general food prohibitions will be found in 2:173, 5:4-5, and 6:121, 138- 146. They are meant for health and cleanliness, but the worst abominations to shun are those of false worship and false speech. Here the question is about food during Pilgrimage. Lawful meat but not game is allowed. 

Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) delivered a Khutbah and said, "O people! Hajj (pilgrimage to the House of Allah) has been made incumbent upon you, so perform Hajj.'' A man inquired: "O Messenger of Allah [SAWW](PBUH), is it prescribed every year?'' He [SAWW](PBUH) remained silent till the man repeated it thrice. Then he [SAWW](PBUH) said, "Had I replied in the affirmative, it would have surely become obligatory, and you would not have been able to fulfill it.'' Afterwards he said, "Do not ask me so long as I do not impose anything upon you, because those who were before you were destroyed on account of their frequent questioning and their disagreement with their Prophets. So when I order you to do something, do it as far as you can; and when I forbid you from doing anything, eschew it.''
