Hanafi Fatwa: Intentionally Passing Wind After Tashahhud Does not Invalidate Salaat

According to the classical Hanafi manual of jurisprudence, Mukhtasar al Quduri, about the one who is praying Salaat:

وَإِنْ تَعَمَّدَ الْحَدَثَ فِي هَذِهِ الْحَالَةِ أَوْ تَكَلَّمَ أَوْ عَمِلَ عَمَلًا يُنَافِي الصَّلَاةَ تَمَّتْ صَلَاتُهُ

"If hadath (passing wind) overtakes him after the tashahhud, he makes wudoo and makes salaam. If in this condition (after tashahhud) he wilfully effects hadath (passing wind) or speak, or performed an action which is inconsistent with salaah, his salaah has been performed."
