سورة Al-Baqarah ( The Cow ) - الآية 196

And perform Hajj (greater pilgrimage) and Umrah (lesser pilgrimage) for Allah; and if you are prevented, send sacrifice whatever is available; and do not shave your heads until the sacrifice reaches its destination; so whoever among you is sick or has an ailment in the head, must pay a compensation by fasting or charity or sacrifice; then when you are in peace – and whoever takes the advantage of combining the Hajj and Umrah, it is compulsory for him to sacrifice whatever is available; and whoever cannot afford it, must fast for three days while on the pilgrimage, and seven when you have returned to your homes; these are ten in all; this decree is for him who is not a resident of Mecca; and keep fearing Allah and know well that Allah’s punishment is severe.
