Khushoo

Khushoo means to pray to Allah from the depth of our heart with full attention in Salah. One gains khushu from a fear of Allah and the sense that He is always watching. It means that one's heart stands before its Lord with humility and submission

Salaah (Prayer) as is defined by the Scholars of Islam is an act of worship consisting of specific sayings accompanying specific actions, at specific times. It begins with "Takbeer" and ends with "Tasleem".
