Are acts of obedience such as "charity, honoring one's parents, and visiting the sick" sufficient to compensate for years of missed fasting and prayer without a valid excuse? And would these acts tip the scale of good deeds on the Day of Judgment?

Scholars differ regarding making up missed prayers without a valid excuse. Some say that repentance, seeking forgiveness, and performing supererogatory prayers are sufficient, while the majority of scholars hold that making them up is obligatory, which is the more cautious approach. Similarly, making up obligatory fasts broken without a valid excuse is required by the majority of scholars, though there is a difference concerning the validity of scholarly consensus on this matter. Some narrations from the Companions, such as Ibn Mas'ud, Ali, and Abu Hurairah, state that making up a fast broken intentionally is not accepted. If the breaking of the fast was due to sexual intercourse, then expiation (kaffarah (definition)) is required in addition to making up the fast. Some scholars also hold that expiation is required for delaying the making up of missed obligations. The fatwa (definition) emphasized that righteous deeds do not compensate for missed prayers and fasts, and that abandoning obligatory duties is a grave sin that requires sincere repentance, along with an abundance of good deeds.
