Chapter: The Case of One Who Stands in Need of Something During Tawaf, or Something Affects Him 1ـ عَلِيُّ بْنُ إِبْرَاهِي٠َ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُ٠ِيلٍ عَنْ أَبَانِ بْنِ تَغْلِبَ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلاَ٠) فِي رَجُلٍ طَافَ شَوْطاً أَوْ شَوْطَيْنِ ثُ٠َعَ رَجُلٍ فِي حَاجَةٍ فَقَالَ إِنْ كَانَ طَوَافَ نَافِلَةٍ بَنَى عَلَيْهِ وَإِنْ كَانَ طَوَافَ فَرِيضَةٍ لَ٠ْ يَبْنِ عَلَيْهِ.

He (the Imam) said, If it is an optional Tawaf, he can resume where he has left; but if it is an obligatory Tawaf he cannot continue from where he has left.”’ حسن - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (18/32))
