Is it permissible for whoever misses a congregational Salah (Prayer) to make up for it after the expiry of its time
bearing in mind that performing Salah during its regular time is a condition of its validity? Besides, is a person excused for not performing Fajr (Dawn) Prayer on time because of being always asleep at that time? Is it permissible for them to make up for Fajr Prayer every day after sunrise? It may be worth mentioning that some people say that Fajr Prayer is not to be made up for in such a case because performing Salah during its regular time is a condition of its validity.
First, it is Wajib (obligatory) on whoever misses a Salah to hasten to make up for it as it is authentically narrated that the Prophet (peace be upon him) said:
Whoever misses a Salah because of sleep or oblivion, they have to offer it when they remember it, there is no Kaffarah (expiation) for it except this.
Second, it is Wajib on a person to follow the necessary mediums that help them to wake up early. For example, they have to use an alarm or ask somebody else who usually wakes up early to awaken them for Fajr Prayer. Being always asleep during the time of Fajr Prayer is not a valid excuse for not performing the concerned Salah on time and performing it only when a person wakes up. Doing the foregoing makes the concerned person liable to the threat which is mentioned in Allah's Saying:
Then, there has succeeded them a posterity who have given up As-Salât (the prayers) [i.e. made their Salât (prayers) to be lost, either by not offering them or by not offering them perfectly or by not offering them in their proper fixed times] and have followed lusts. So they will be thrown in Hell.
So woe unto those performers of Salât (prayers) (hypocrites),
Those who delay their Salât (prayer from their stated fixed times).
