Answered by Shaykh Faraz Rabbani
Question: If an obligatory prayer is considerably delayed to an extent that upon completing the prayer (or in the final rak’aa), the time for the next prayer arrives, is the former prayer accepted as being prayed on time? In other words, when one commences the delayed prayer, he is on time (i.e. with 3 or 4 minutes left before the next salah) but when the prayer is finished, the next salah time has already arrived (e.g. in the 4th rak’aa of Asr prayer, the time of maghrib has commenced), is his Asr prayer considered “on time”? or is it a “make up prayer”? I know praying on time is important, but what if a person experiences the above situation (like I did) for the 1st time in my life?
Answer: Walaikum assalam wa rahmatullahi wa barakatuh,
It is obligatory to begin and end each obligatory prayer within its time. However, only Fajr is invalidated by the exiting of its time. Asr, Maghrib, and Isha prayers are sinful to delay to their disliked time without genuine excuse.
The Prophet (Allah bless him and give him peace) said that “Prayer at its time,” is the best of actions after belief (iman) itself, so one should take the means to perform it at the right time.
And Allah alone gives success.
