Are religious books and Qur'anic surahs considered impure after being touched by unpurified hands? And does not purifying them affect the validity of one's Islam after uttering the Shahadatayn?

Abandoning prayer is not a solution to a problem; rather, it is a help to the Muslim. Abandoning it is a grave error due to its contradiction of exalting the rituals of Allah. This abandonment does not amount to disbelief unless it stems from disdain. The cure for obsessive whispers (waswas) is to completely disregard them and occupy one's time with knowledge, listening to the Quran, engaging in sports, and studying the biographies of the Salaf (pious predecessors).
