Praying in the bus during the journey

While on the bus, try to get off the bus and pray. If the bus driver is told to stop the car and pray. If the bus does not stop, he will stand and pray. If unable to stand, then pray sitting on a seat. If you pray sitting, you do not have to perform the prayer later. But if facing the Qibla can not complete the prayer. Then the prayer should be repeated. If you read facing the Qibla, then you don't have to do Qaza. Yes, if one cannot pray while sitting, then one will pray by pointing. However, this prayer must be performed later.

If there is no arrangement to perform ablution, then perform tayammum and pray. After praying with tayammum, if you get water later, you do not have to repeat the prayer thinking that the prayer was not performed because of the tayammum. Rather, the prayer is purified by tayammum.

And it is not necessary for women to open their hands during prayer. Namaz can be read without opening the mouth and hands. no problem
