Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 4
وَ بِهَذَا اَلْإِسْنَادِ عَنْ عُثْمَانَ عَنِ اِبْنِ مُسْكَانَ عَنْ مَالِكِ بْنِ أَعْيَنَ قَالَ: سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ عَمَّنْ تَوَضَّأَ وَ نَسِيَ اَلْمَضْمَضَةَ وَ اَلاِسْتِنْشَاقَ ثُمَّ ذَكَرَ بَعْدَ مَا دَخَلَ فِي صَلاَتِهِ قَالَ« لاَ بَأْسَ».
Through the same chain of transmission, from ʿUthman, from Ibn Muskan, from Malik ibn Aʿyan, who said:
I asked Abu Abdullah عليه السلام about someone who performed ablution (Wuduʾ) and forgot to rinse their mouth (Madmada) and sniff water into their nose (Istinshaq), and then remembered after starting their prayer. Imam عليه السلام said: "There is no harm."
