Is repentance for many missed prayers sufficient, or must they be made up?

Whoever abandons prayer intentionally is considered a disbeliever according to the more accurate of the two scholarly opinions. If such a person repents and returns to Allah, they are not obligated to make up the prayers they missed. However, whoever misses prayers due to an excuse, such as fainting or the like, must make up what they missed upon regaining consciousness. It is advised to repent, perform many supererogatory acts of worship (Nawafil), give charity, and make up the missed prayers as a precautionary measure and to avoid scholarly dispute, if possible.
