Muwatta Imam Malik Book of Hajj, Hadith 104
Yahya related to me from Malik from Ibn Shihab from Salim ibn Abdullah that Abdullah ibn Umar said, "Some one who is detained by sickness before he has got to the House cannot leave ihram until he has done tawaf of the House and say between Safa and Marwa."
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ سَالِمِ بْنِ عَبْدِ اللَّهِ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّهُ قَالَ مَنْ حُبِسَ دُونَ الْبَيْتِ بِمَرَضٍ فَإِنَّهُ لاَ يَحِلُّ حَتَّى يَطُوفَ بِالْبَيْتِ وَبَيْنَ الصَّفَا وَالْمَرْوَةِ .
