Start From Here
NIYYAH:
Before starting the prayer, perform ablution (wudu) or when necessary, take a full bath ghusl. Ensure that your clothes and the place for prayer are clean. Make sure your body is covered properly. For women, in addition to the hands, face, and feet, everything else should be covered during prayer. Face the Qibla {the direction of the Kaaba}.
For the prayer you intend to perform silently make the intention in your mind or say it quietly. During the prayer, keep your eyes focused on the place where you will prostrate, except when mentioning it.
Make sure your feet are facing the Qibla.
Men should keep their feet apart with a minimum width of four fingers, and women should keep their feet together during the prayer.
