What is the ruling regarding a girl's feeling of dampness in her clothes after performing istinja’, where she suspects it is urine or an impure discharge, despite the absence of smell or color, and is it possible for this to be from the remnants of istinja’ water? And what should she do about her frequent waswas (obsessive whispers) during prayer, such as forgetting the rak'ahs or sujud, or reciting Al-Fatiha, or performing the taslim?

We advise you to completely and thoroughly disregard intrusive thoughts (waswasa). If your feeling that a discharge has occurred is merely a doubt or an intrusive thought, then do not pay attention to it. If you are certain that something has come out, but you doubt whether it is urine or not, do not consider it urine, and you are not required to perform istinja (definition)' (washing after relieving oneself) merely based on doubt. If the wetness could be from the remnants of istinja', then nothing is required of you. Do not pay attention to doubt concerning the omission of a pillar (rukn) or an obligation (wajib (definition)) of prayer.
