Arabic hadith text
وَعَنْ أَبِي هُرَيْرَةَ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا وَجَدَ أَحَدُكُمْ فِي بَطْنِهِ شَيْئًا فَأَشْكَلَ عَلَيْهِ أَخَرَجَ مِنْهُ شَيْءٌ أَمْ لَا فَلَا يَخْرُجَنَّ مِنَ الْمَسْجِدِ حَتَّى يَسْمَعَ صَوْتًا أَوْ يَجِدَ رِيحًا» . رَوَاهُ مُسلم
Translation
Abū Hurayra reported that the Messenger of God said: ‘If one of you feels something in his abdomen and is unsure whether anything has come out, he should not leave the mosque unless he hears a sound or detects an odor.’ Muslim transmitted it.
