مُحَمَّدُ بْنُ عَلِيِّ بْنِ مَحْبُوبٍ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنِ اَلْحَسَنِ بْنِ رَاشِدٍ قَالَ قَالَ اَلْفَقِيهُ اَلْعَسْكَرِيُّ عَلَيْهِ اَلسَّلاَمُ: «لَيْسَ فِي اَلْغُسْلِ وَ لاَ فِي اَلْوُضُوءِ مَضْمَضَةٌ وَ لاَ اِسْتِنْشَاقٌ».
Narrated by Muhammad ibn Ali ibn Mahbub, from Muhammad ibn Isa, from al-Hasan ibn Rashid, who said:
The jurist Imam al-Askari عليه السلام said: "There is no (obligatory) rinsing of the mouth (madmadah) or sniffing water into the nose (istinshaq) in ghusl or wudu."
