The reward for praying 'Isha' and Fajr in congregation and standing in night prayer

Question:
May Allah reward you. He says: He who the hadith. Does this prayer suffice for standing in night prayer if a person is consistent in standing in night prayer but forgets it at times or sleeps through it?

Answer:
Yes, the hadith is valid, and it is regarding the performance of obligatory duties. It is essential to perform the obligatory duties; voluntary acts are not accepted until the obligatory ones are performed. So, whoever prays 'Isha' in congregation and prays Fajr in congregation, he gains a great reward. However, it does not replace standing in night prayer. Standing in night prayer has a great virtue, and its virtue is added to the virtue of the one who prays 'Isha' in congregation and prays Fajr in congregation. But if a person intends to get up in the last part of the night, yet sleep overcomes him or a preoccupation prevents him from doing so, and his intention remains, then he earns what he intended. We do not assume that he slept or fell ill and was unable to get up, but his intention to stand in prayer remains; if he had been able to, this would be recorded for him as what he used to do, validly, because he left it off while his intention remained, but an excuse prevented him.
