Is the prayer of one who repeated his prayer and ablution more than once due to moisture that only appears by wiping, then performed ablution with drinking water while air bubbles exited from her vagina, and prayed based on the principle that the one afflicted by whisperings (waswas) should adopt the easiest opinions, valid? And is it sufficient for one who purified herself from water with a foul odor that touched her inner clothes and thigh by merely wiping her thigh with water?

Vaginal discharge, known as vaginal moisture, is pure. It does not necessitate istinja' (washing of private parts), but it does nullify wudu' (ablution) if it exits to the outer vulva. Wudu' is not nullified by what remains inside the vagina. If there is doubt about the discharge having exited, there is no need to investigate, because the default assumption is that it has not exited. Wudu' is not nullified merely by a sensation of bubbles; rather, certainty of the emission of gas is required. Water that gets on clothes is pure and does not become impure if its smell changes.
