What is the ruling on one who omits washing the hands after waking up from sleep, concerning the validity of his ritual purity for prayer, taking into account the view of those who deem it obligatory? And is it sufficient to wash them before performing ablution?

The majority of scholars hold that washing the hands upon waking is not obligatory, so there is no sin in omitting it. This washing is simple and only takes a few seconds. We advise you to adhere to supplication and humble entreaty, and to distract yourself from these whisperings (waswas). It is also recommended to consult a trusted psychiatrist.
