Can I pray on a bus or train?

Voluntary prayers: easy

The Prophet ﷺ used to pray voluntary prayers on his mount, facing whichever direction it went, nodding his head for bowing and prostration, but he never did that for the obligatory prayers (Sahih al-Bukhari 1097). When he wanted to pray an obligatory prayer, he dismounted and faced the qibla (Sahih al-Bukhari 400). Scholars apply this to buses, trains and cars: sunnah prayers and witr can be prayed seated, in any direction.

Obligatory prayers on a train

Trains often have room. The space by the doors, a vestibule between carriages, or a quiet end of a carriage may let you stand, face the qibla, bow and put your forehead down. If you can do all that, your prayer is complete, and all the schools accept it. A folded jacket works as a mat. Long-distance and sleeper trains usually make this easy.

Obligatory prayers on a bus

On a bus it's rarely possible to stand and prostrate, so plan around it:

• Pray before you board if the prayer time has come in.
• Use rest stops: long-distance buses usually stop every few hours.
• Combine: as a traveler, most schools let you pray Dhuhr with Asr and Maghrib with Isha, in either prayer's time. The Hanafi school doesn't combine on a journey, but you can pray one at the end of its time and the next at the start of its own. See Can I combine prayers because of my class schedule?

If there's truly no other way

If the time will run out before you can get off, don't let the prayer pass. Pray in your seat: face the qibla at the start if you can, stand if possible, otherwise sit and lean forward for bowing, a little lower for prostration. The Prophet ﷺ said, "Pray while standing and if you can't, pray while sitting" (Sahih al-Bukhari 1117).

Scholars differ on whether you repeat it later. Many Shafi'is, and some Hanafis, say to repeat it once you can pray normally, to be safe. Others, including many Hanbali scholars, say a prayer done to the best of your ability is complete. The same rules apply in the air and at sea.
