أَحْمَدُ بْنُ مُحَمَّدٍ عَنْ عَلِيِّ بْنِ الْحُكْمِ عَنْ سَيْفِ بْنِ عُمَيْرَةَ عَنْ أَبِي بَكْرٍ الْحَضْرَمِيِّ عَنْ أَبِي عَبْدِ اللَّهِ عَلَيْهِ السَّلَامُ قَالَ: لَيْسَ عَلَيْكَ مَضْمَضَةٌ وَلَا اسْتِنْشَاقٌ لِأَنَّهُمَا مِنَ الْجَوْفِ.
Narrated by Ahmad ibn Muhammad, from Ali ibn al-Hakam, from Saif ibn Umayrah, from Abu Bakr al-Hadrami, from Abu Abdullah عليه السلام, who said:
Imam عليه السلام said: "You are not required to rinse your mouth (madmadah) or sniff water into your nose (istinshaq), as they are considered part of the inner body (al-jawf)."
