Is it obligatory to repeat a prayer that was performed with a continuous emission of gas if the emission stopped after the prayer and before its time expired, knowing that he was unaware of its cessation?

If the emission of wind is most of the time and its timing is irregular, then it takes the ruling of one afflicted with perpetual impurity (sahib al-salas); he performs ablution for the time of each prayer and prays, and he is not required to repeat the prayer. It is advised to ignore these whispers (waswas).
