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 ḥajj and ʿumrah for Allāh. But if you are prevented, then [offer] what can be obtained with ease of sacrificial animals. And do not shave your heads until the sacrificial animal has reached its place of slaughter. And whoever among you is ill or has an ailment of the head [making shaving necessary must offer] a ransom of fasting [three days] or charity¹ or sacrifice.² And when you are secure,³ then whoever performs ʿumrah [during the ḥajj months]⁴ followed by ḥajj [offers] what can be obtained with ease of sacrificial animals. And whoever cannot find [or afford such an animal] - then a fast of three days during ḥajj and of seven when you have returned [home]. Those are ten complete [days]. This is for those whose family is not in the area of al-Masjid al-Ḥarām. And fear Allāh and know that Allāh is severe in penalty.
