Prayer is not accepted without wuḍūʾ
Messenger of Allah ﷺ said, "The prayer of a person who does Hadath (passes urine, stool or wind) is not accepted till he performs the ablution." A person from Hadaramout asked Abu Huraira, "What is 'Hadath'?" Abu Huraira replied, " 'Hadath' means the passing of wind."
قَالَ رَسُولُ اللَّهِ ﷺ «لاَ تُقْبَلُ صَلاَةُ مَنْ أَحْدَثَ حَتَّى يَتَوَضَّأَ۔» قَالَ رَجُلٌ مِنْ حَضْرَمَوْتَ: مَا الْحَدَثُ يَا أَبَا هُرَيْرَةَ؟ قَالَ: فُسَاءٌ أَوْ ضُرَاطٌ۔
