wudu
9ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنِ ابْنِ أُذَيْنَةَ عَنْ أَبِي أُسَامَةَ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنِ الْقَيْ‏ءِ هَلْ يَنْقُضُ الْوُضُوءَ قَالَ لاَ.
9. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Ibn ’Udhaynah from abu ‘Usamah who has said the following: “I once asked abu ‘Abd Allah (a.s.), about vomiting if it invalidates Wudu’ or not. He (the Imam) said, ‘No, it does not invalidate one’s Wudu’.’”
