عَنْ حُصَيْنٍ الْمُزَنِيِّ قَالَ: قَالَ عَلِيُّ بْنُ أَبِي طَالِبٍ رَضِيَ اللَّهُ عَنْهُ عَلَى الْمِنْبَرِ: أَيُّهَا النَّاسُ! إِنِّي سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ يَقُولُ: ((لَا يَقْطَعُ الصَّلَاةَ إِلَّا الْحَدَثُ، لَا أَسْتَحِيِيكُمْ مِمَّا لَا يَسْتَحِيِي مِنْهُ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ، قَالَ: وَالْحَدَثُ أَنْ يَفْسُوَ أَوْ يَضْرِطَ))
Sayyiduna Ali ibn Abi Talib (may Allah be pleased with him) said on the pulpit: O people! Indeed, I heard the Messenger of Allah (peace and blessings be upon him) say: Nothing breaks the prayer except hadath (a state of impurity). I do not feel shy to mention that which the Messenger of Allah (peace and blessings be upon him) was not shy to mention. Hadath is when a person passes wind silently or audibly.
