Will a Muslim's deficient prayer be completed by the reward of Laylat al-Qadr, which is better than a thousand months?

On the Day of Resurrection, people will first be held accountable for their prayers. Allah Almighty says to His angels: "Look at My servant's prayer; did he complete it or fall short? If it was complete, record it as complete. If there was any deficiency in it, He says: Look, does My servant have any voluntary prayers? If he has voluntary prayers, He says: Complete My servant's obligatory prayer for him." Then, deeds will be taken in this manner. This Hadith indicates that deficiencies in obligatory duties are completed by voluntary acts, such as observing Laylat al-Qadr (the Night of Decree). The deficiency meant here refers to shortcomings in the prayer's humility, bowing, and prostration, and not to the one who abandons prayer, as nothing can compensate for an obligatory duty.
