Al-Baqarah 2:196 واتموا الحج والعمرة لله فان احصرتم فما استيسر من الهدي ولا تحلقوا رءوسكم حتى يبلغ الهدي محله فمن كان منكم مريضا او به اذى من راسه ففدية من صيام او صدقة او نسك فاذا امنتم فمن تمتع بالعمرة الى الحج فما استيسر من الهدي فمن لم يجد فصيام ثلاثة ايام في الحج وسبعة اذا رجعتم تلك عشرة كاملة ذالك لمن لم يكن اهله حاضري المسجد الحرام واتقوا الله واعلموا ان الله شديد العقاب ١٩٦

Complete Hajj and 'Umrah for Allah. And if you are prevented from doing so, then make the offering which is available to you,¹ and do not shave your heads until the offering reaches its appointed place.²If any of you should have to shave your head before that because of illness, or injury to the head, then you should make redemption by fasting, or almsgiving, or ritual sacrifice.³ And when you are secure,⁴ then he who avails of 'Umrah before the time of Hajj shall give the offering he can afford; and if he cannot afford the offering, he shall fast for three days during Hajj and for seven days after he returns home; that is, ten days in all. This privilege is for those whose families do not live near the Holy Mosque.⁵ Guard against violating these ordinances of Allah and be mindful that Allah is severe in chastisement.
