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 complete the Hajj or 'umra in the service of Allah. But if ye are prevented (From completing it), send an offering for sacrifice, such as ye may find, and do not shave your heads until the offering reaches the place of sacrifice. And if any of you is ill, or has an ailment in his scalp, (Necessitating shaving), (He should) in compensation either fast, or feed the poor, or offer sacrifice; and when ye are in peaceful conditions (again), if any one wishes to continue the 'umra on to the hajj, He must make an offering, such as he can afford, but if he cannot afford it, He should fast three days during the hajj and seven days on his return, Making ten days in all. This is for those whose household is not in (the precincts of) the Sacred Mosque. And fear Allah, and know that Allah Is strict in punishment.
