"I said: 'O Messenger of Allah! Tell me about ablution.' He said: 'Perform ablution properly and sniff water up into your nostrils, thoroughly, unless you are fasting.'" (Using translation from Ibn Mājah 407)  

قُلْتُ يَا رَسُولَ اللهِ أَخْبِرْنِي عَنِ الْوُضُوءِ قَالَ «أَسْبَغِ الْوُضُوءَ وَبَالِغْ فِي الِاسْتِنْشَاقِ إِلَّا أَنْ تَكُونَ صَائِمًا»
