The Book of Purification and its Sunnah
1/114. Chapter:
What was narrated of the prohibition for the one holding urine or stool from praying
Sunan Ibn Majah
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُصَفَّى الْحِمْصِيُّ، حَدَّثَنَا بَقِيَّةُ، عَنْ حَبِيبِ بْنِ صَالِحٍ، عَنْ أَبِي حَىٍّ الْمُؤَذِّنِ، عَنْ ثَوْبَانَ، عَنْ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ أَنَّهُ قَالَ " لاَ يَقُومُ أَحَدٌ مِنَ الْمُسْلِمِينَ وَهُوَ حَاقِنٌ حَتَّى يَتَخَفَّفَ " .
It was narrated from Thawban that: The Messenger of Allah said: "No one among the Muslims should stand to pray when he is suppressing (the need to urinate or defecate), until he has to relieve himself."
