I was on a long journey and we were in a European airport. The time for the plane to take off was also the time for Zuhr prayer to begin, according to the prayer timetable for that city. Before we got on board the plane, ten minutes before takeoff, we prayed Zuhr and ‘Asr with some other brothers. One of the brothers criticized us and told us that we should have prayed on board the plane after making sure that the time for prayer had begun. Is our prayer valid, knowing that there was no suitable place for praying on the plane and we were going to arrive in our country at night?.
It is permissible for a traveller to join Zuhr and ‘Asr, and Maghrib and ‘Isha’, at the time of the earlier or later prayer, according to whatever is easier for him.
Secondly:
There are set times for the five daily prayers, the beginning and end of which are clearly defined, as Allaah says (interpretation of the meaning):
“Verily, As‑Salaah (the prayer) is enjoined on the believers at fixed hours”
[al-Nisa’ 4:103]
i.e., there are set times for it, and it is not permissible for the Muslim to offer any prayer before the time for it has begun. If he does that, it is not valid, according to scholarly consensus.
Based on this, you have to repeat Zuhr and ‘Asr, because you offered them before the time for them began.
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) was asked about the ruling on offering a prayer before the time for it has begun.
He replied:
Offering a prayer before the time for it has begun is not valid, even if it was only one minute before the time for it. If a person says the opening takbeer before the time, then his prayer is not valid, because Allaah says (interpretation of the meaning):
“Verily, As‑Salaah (the prayer) is enjoined on the believers at fixed hours”
[al-Nisa’ 4:103]
i.e., strictly-defined times. So the prayer is not valid if it is offered before its time, and the prayer that you offered before its time must be repeated. And Allaah is the source of strength. End quote from Majmoo’ Fataawa al-Shaykh Ibn ‘Uthaymeen (12/216).
He also said: Prayer is not valid if done before its time, according to the consensus of the Muslims. If a person offers a prayer ahead of time, if he did that deliberately then his prayer is invalid, and he is not free of sin. If he did not do it deliberately, because he thought that the time for it had begun, then he is not a sinner, and his prayer is regarded as naafil (supererogatory), but he has to repeat it, because one of the conditions of prayer is that the time for it should have begun.
