Hadith 82
قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ : " إِذَا تَوَضَّأَ أَحَدُكُمْ، فَلْيَسْتَنْشِقْ بِمَنْخِرَيْهِ مِنْ مَاءٍ، ثُمَّ لِيَنْتَثِرْ "
And the Messenger of Allah, peace and blessings be upon him, said: "When any one of you performs ablution, let him draw water into his nostrils and then expel it."
