Combining Zhuhr with `Asr Prayer
If a person had combined two prayers, Zhuhr (Noon) and `Asr (Afternoon) prayers, while travelling then he reached home before the sunset, does he have to repeat the `Asr Prayer before its due time is out?
Almighty Allah says:
And when you travel throughout the land, there is no blame upon you for shortening the prayer. (An-Nisaa’ 4:101)
Jam` (combining) prayer means that a Muslim combines or joins up two prayers, Zuhur and `Asr, or Maghrib and `Isha’, at the time of the earlier or the latter of the two prayers (Zuhur and `Asr at Zuhur or `Asr; Maghrib and `Isha’ at Maghrib or at `Isha’).
Anas ibn Malik (may Allah be pleased with him) narrated that the Prophet (peace be upon him) joined Maghrib and `Isha’ prayers when travelling.” (Al-Bukhari)
Combining prayers is permissible for travelers and for non-travelers if it is too difficult to offer every prayer on time, such as one who is sick, or if there is rain, or one is busy with some work that he cannot delay in order to pray, such as a student taking an exam or a doctor who is doing surgery and so on.
Responding to this question, Dr. Muhammad Salah explains the permissibility of combining tow prayers whether in travelling or due to a valid excuse. Then, he talks about the ruling of repeating the `Asr prayer before the sunset in case of combining it with Zhuhr Prayer.
