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

Accomplish the Hajj and the ‘Umrah for Allah, but if you are restricted, then (sacrifice) whatever animal of offering is available, and do not shave your heads until the offering reaches its place. But if anyone of you is ill, or has some trouble with his scalp, then there is a ransom through fasting or alms giving.And when you are safe, then, whoever avails the advantage of the ‘Umrah along with the Hajj shall make an offering of whatever animal is available. However, any one who finds none shall fast for three days during Hajj, and for seven days when you return; thus they are ten in all. This is for him whose family folk are not residents of Al-Masjid-ul-Harām. Fear Allah and be aware that Allah is severe in punishment.
