O Allah, forgive him? O Allah, take mercy on him, until he turns away, or he is defiled. He was asked: what is meant by defilement? He replied: he breaks wind gently or loudly. (Using translation from Abū Dāʾūd 471)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا يَزَالُ الْعَبْدُ فِي صَلَاةٍ مَا دَامَ يَنْتَظِرُ الصَّلَاةَ تَقُولُ الْمَلَائِكَةُ اللهُمَّ اغْفِرْ لَهُ اللهُمَّ ارْحَمْهُ مَا لَمْ يَنْصَرِفْ أَوْ يُحْدِثْ فَقِيلَ لَهُ مَا يُحْدِثُ؟ قَالَ يَفْسُو أَوْ يَضْرِطُ
