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

Perform the pilgrimage and the visit (to Makka) for Allah. And if ye are prevented, then send such gifts as can be obtained with ease, and shave not your heads until the gifts have reached their destination. And whoever among you is sick or hath an ailment of the head must pay a ransom of fasting or almsgiving or offering. And if ye are in safety, then whosoever contenteth himself with the visit for the pilgrimage (shall give) such gifts as can be had with ease. And whosoever cannot find (such gifts), then a fast of three days while on the pilgrimage, and of seven when ye have returned; that is, ten in all. That is for him whoso folk are not present at the Inviolable Place of Worship. Observe your duty to Allah, and know that Allah is severe in punishment.
