Hadith 35B2

قَالَ يَحْيَى : وَسُئِلَ مَالِك ، عَنْ رَجُلٍ نَسِيَ أَنْ يَتَمَضْمَضَ وَيَسْتَنْثِرَ حَتَّى صَلَّى ، قَالَ : لَيْسَ عَلَيْهِ أَنْ يُعِيدَ صَلَاتَهُ ، وَلْيُمَضْمِضْ وَيَسْتَنْثِرْ مَا يَسْتَقْبِلُ إِنْ كَانَ يُرِيدُ أَنْ يُصَلِّيَ
Yahya said: Imam Malik, may Allah have mercy on him, was asked about a person who forgot to rinse his mouth or put water in his nose during ablution and then performed the prayer. Imam Malik, may Allah have mercy on him, said: His prayer is valid; it is not necessary for him to repeat the prayer, but for the next prayer he should rinse his mouth or put water in his nose.
