Can we pray salat while in a moving car thats because there is no place to stop and pray?
Praise be to Allah.
According to a report narrated by Muslim, he said:
"The (whole) earth has been made good for me, a means of purification and a mosque (or place of prayer); so wherever a man may be when the time for prayer comes, let him pray wherever he is."
(Saheeh Muslim, no. 521)
The entire world is a suitable place to prostrate oneself; the scholars have made no exceptions except very few, such as graveyards and lavatories. Wherever a Muslim is when the time for prayer comes, he should pray: in a mosque, if possible, or else in a hallway or park, on a sidewalk or in a parking lot, or in a corner of a store.
