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

And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad صلى الله عليه وسلم), the Hajj and ‘Umrah (i.e. the pilgrimage to Makkah) for Allâh. But if you are prevented (from completing them), sacrifice a Hady (animal, i.e. a sheep, a cow, or a camel) such as you can afford, and do not shave your heads until the Hady reaches the place of sacrifice. And whosoever of you is ill or has an ailment in his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either observing Saum (fasts) (three days) or giving Sadaqah (charity - feeding six poor persons) or offering sacrifice (one sheep). Then if you are in safety and whosoever performs the ‘Umrah in the months of Hajj before (performing) the Hajj, (i.e. Hajj-at-Tamattu‘ and Al-Qirân), he must slaughter a Hady such as he can afford, but if he cannot afford it, he should observe Saum (fasts) three days during the Hajj and seven days after his return (to his home), making ten days in all. This is for him whose family is not present at Al-Masjid-Al-Harâm (i.e. non-resident of Makkah). And fear Allâh much and know that Allâh is Severe in punishment.¹
