Appears 5 times in the Quran. (Root: هدي)
  1. And accomplish the pilgrimage and the visit for Allah, but if, you are prevented, (send) whatever offering is easy to obtain, and do not shave your heads until the offering reaches its destination; but whoever among you is sick or has an ailment of the head, he (should effect) a compensation by fasting or alms or sacrificing, then when you are secure, whoever profits by combining the visit with the pilgrimage (should take) what offering is easy to obtain; but he who cannot find (any offering) should fast for three days during the pilgrimage and for seven days when you return; these (make) ten (days) complete; this is for him whose family is not present in the Sacred Mosque, and be careful (of your duty) to Allah, and know that Allah is severe in requiting (evil).

  2. O you who believe! do not violate the signs appointed by Allah nor the sacred month, nor (interfere with) the offerings, nor the sacrificial animals with garlands, nor those going to the sacred house seeking the grace and pleasure of their Lord; and when you are free from the obligations of the pilgrimage, then hunt, and let not hatred of a people-- because they hindered you from the Sacred Masjid-- incite you to exceed the limits, and help one another in goodness and piety, and do not help one another in sin and aggression; and be careful of (your duty to) Allah; surely Allah is severe in requiting (evil).

  3. O you who believe! do not kill game while you are on pilgrimage, and whoever among you shall kill it intentionally, the compensation (of it) is the like of what he killed, from the cattle, as two just persons among you shall judge, as an offering to be brought to the Kaaba or the expiation (of it) is the feeding of the poor or the equivalent of it in fasting, that he may taste the unwholesome result of his deed; Allah has pardoned what is gone by; and whoever returns (to it), Allah will inflict retribution on him; and Allah is Mighty, Lord of Retribution.

  4. Allah has made the Kaaba, the sacred house, a maintenance for the people, and the sacred month and the offerings and the sacrificial animals with garlands; this is that you may know that Allah knows whatever is in the heavens and whatever is in the earth, and that Allah is the Knower of all things.

  5. It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.
