The Conditions for the Validity of Prayer on an Airplane and Its Manner

Question:
May Allah reward you with good and do you well. A listener says: Dr. Ramadan, who resides in the Kingdom, asks and says: I was traveling, and the airplane took off before the call to Maghrib prayer, and it landed after the call to 'Isha' prayer. I prayed Maghrib on the airplane, bowing and prostrating with gestures, knowing that I did not know the direction of the qiblah. Is the prayer valid in that case? Or was it obligatory for me to combine Maghrib with 'Isha'? May Allah reward you with good.

Answer:
If the airplane took off before the sun set, then you combine Maghrib with 'Isha' by delaying the prayer, because Maghrib became obligatory for you while you were in the air, and your prayer on the airplane, as you mentioned, involves hardship and a deficiency in the prayer, or the prayer may not be valid in that state.
As for if Maghrib became obligatory while you were on the ground—the sun set and the airplane had not taken off and you were on the ground—then you pray Maghrib in its time while you are on the airplane. However, when you want to pray, you look for a place on the airplane where you can perform the prayer in the prescribed manner, facing the qiblah, bowing, prostrating, and standing. You do this by asking the pilots about the direction of the qiblah, and they will inform you, and you go to a place on the airplane where you can pray. Yes.
