[Machine] The Messenger of Allah ﷺ said, "Gargling and sniffing water into the nose are essential parts of ablution that cannot be skipped." Al-Shaykh reported it and Isma'il ibn Bishr al-Balkhi narrated from 'Isam (ibn Yusuf al-Balkhi) something similar to that, except that he said, "Required part of ablution that the prayer cannot be completed without it." Abu Bakr al-Faqih informed us, "I am 'Ali ibn 'Umar Al-Hafiz, and 'Isam narrated it as something specific and there was some confusion about it. The correct narration is from Ibn Juraij from Sulayman ibn Musa who transmitted it from the Prophet ﷺ, 'Whoever performs ablution should gargle and sniff water into the nose.'"
أَنَّ رَسُولَ اللهِ ﷺ قَالَ الْمَضْمَضَةُ وَالِاسْتِنْشَاقُ مِنَ الْوُضُوءِ الَّذِي لَا بُدَّ مِنْهُ قَالَ الشَّيْخُ وَرَوَاهُ إِسْمَاعِيلُ بْنُ بِشْرٍ الْبَلْخِيُّ عَنْ عِصَامٍ نَحْوَهُ إِلَّا أَنَّهُ قَالَ مِنَ الْوُضُوءِ الَّذِي لَا تَتِمُّ الصَّلَاةُ إِلَّا بِهِ أَخْبَرَنَا أَبُو بَكْرٍ الْفَقِيهُ أنا عَلِيُّ بْنُ عُمَرَ الْحَافِظُ قَالَ تَفَرَّدَ بِهِ عِصَامٌ وَوَهِمَ فِيهِ وَالصَّوَابُ عَنِ ابْنِ جُرَيْجٍ عَنْ سُلَيْمَانَ بْنِ مُوسَى مُرْسَلًا عَنِ النَّبِيِّ ﷺ مَنْ تَوَضَّأَ فَلْيُمَضْمِضْ وَلْيَسْتَنْشِقْ
