Does repentance invalidate what preceded it of abandoning prayer, and is it obligatory to make up missed prayers, and how is the make-up done according to the four Imams?

Whoever repents with sincere repentance, their repentance erases what came before it, and Allah forgives all sins for those who repent. As for one who abandons prayer while denying its obligation, they have disbelieved, and a disbeliever is not required to make up the prayers they missed. However, for one who abandons prayer out of laziness, the jurists have differed regarding the obligation of making it up. The fatwa (definition) adopted by us is the necessity of making it up, and this is the view of the Four Imams and the majority of their followers. Information on how to make up these prayers can be found in related fatwas.
