Place one hand on top of another while praying below the navel

According to Ali ibn AbuTalib, it is a sunnah or tradition of Prophet Muhammad to place one hand on top of the other while praying. This should be done below the navel. This practice has been passed down from generation to generation and is still practiced today by Muslims all over the world. It is important for Muslims to follow this sunnah as it was taught by Prophet Muhammad himself and it helps bring unity among believers when they are all following similar practices during prayer.
