باب الْمُبَالَغَةِ فِي الاِسْتِنْشَاقِ وَالاِسْتِنْثَارِ
Sunan Ibn Majah 407
It was narrated from 'Asim bin Laqit bin Sabrah that his father said:
"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.'"
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا يَحْيَى بْنُ سُلَيْمٍ الطَّائِفِيُّ، عَنْ إِسْمَاعِيلَ بْنِ كَثِيرٍ، عَنْ عَاصِمِ بْنِ لَقِيطِ بْنِ صَبِرَةَ، عَنْ أَبِيهِ، قَالَ قُلْتُ يَا رَسُولَ اللَّهِ أَخْبِرْنِي عَنِ الْوُضُوءِ، ‏.‏ قَالَ ‏ "‏ أَسْبِغِ الْوُضُوءَ وَبَالِغْ فِي الاِسْتِنْشَاقِ إِلاَّ أَنْ تَكُونَ صَائِمًا ‏"‏ ‏.‏
