And complete the Hajj and ‘umrah for Allah . But if you are prevented, then [offer] what can be obtained with ease of sacrificial animals. And do not shave your heads until the sacrificial animal has reached its place of slaughter. And whoever among you is ill or has an ailment of the head [making shaving necessary must offer] a ransom of fasting [three days] or charity or sacrifice. And when you are secure, then whoever performs ‘umrah [during the Hajj months] followed by Hajj [offers] what can be obtained with ease of sacrificial animals. And whoever cannot find [or afford such an animal] – then a fast of three days during Hajj and of seven when you have returned [home]. Those are ten complete [days]. This is for those whose family is not in the area of al-Masjid al-Haram. And fear Allah and know that Allah is severe in penalty.
Surat Al-Baqarah 2:196
And if We had decreed upon them, “Kill yourselves” or “Leave your homes,” they would not have done it, except for a few of them. But if they had done what they were instructed, it would have been better for them and a firmer position [for them in faith].
Surat An-Nisa 4:66
O you who have believed, do not violate the rites of Allah or [the sanctity of] the sacred month or [neglect the marking of] the sacrificial animals and garlanding [them] or [violate the safety of] those coming to the Sacred House seeking bounty from their Lord and [His] approval. But when you come out of ihram, then [you may] hunt. And do not let the hatred of a people for having obstructed you from al-Masjid al-Haram lead you to transgress. And cooperate in righteousness and piety, but do not cooperate in sin and aggression. And fear Allah ; indeed, Allah is severe in penalty.
Surat Al-Ma’idah 5:2
And recite to them the story of Adam’s two sons, in truth, when they both offered a sacrifice [to Allah ], and it was accepted from one of them but was not accepted from the other. Said [the latter], “I will surely kill you.” Said [the former], “Indeed, Allah only accepts from the righteous [who fear Him].
Surat Al-Ma’idah 5:27
Say, “Indeed, my prayer, my rites of sacrifice, my living and my dying are for Allah , Lord of the worlds.
Surat Al-Anam 6:162
And when he reached with him [the age of] exertion, he said, “O my son, indeed I have seen in a dream that I [must] sacrifice you, so see what you think.” He said, “O my father, do as you are commanded. You will find me, if Allah wills, of the steadfast.”
Surat As-Saffat 37:102
So pray to your Lord and sacrifice [to Him alone].
Surat Al-Kawthar 108:2
