"Successful indeed are the believers. Those who offer their salah (prayer) with all the solemnity and full submissive. " [Suratul - Mua'minun 23:1-2]
Khushua is a feeling in the heart. It is humility, tranquility and submission to Allah...The heart must be filled with humility when we stand before Allah. The Muslim must acknowledge his weakness before Allah. He must know that it is Allah who forgives the sins that he has committed. He must realize that Allah is the Master and he is the Slave.
The foremost quality that a believer must have in order to achieve this success is Khushua - humility in prayer. According to the tafseer of Imam Qurtubi, before Allah revealed this verse to the Prophet SAW, the muslims would turn to the right and left while they were praying. After these verses were revealed, they stopped this practice, and would only look at the place in front of them. Rasulullah SAW would look at the place of prostration during his prayers.
Khushua is the first thing that usually departs from the prayer. As a result, there will be no tranquility in the Salah. If we are not mindful, we will not get the full reward of making Salah. If we remember this at the time of prayer, our prayer should be more beneficial for us.
Allah made khushua a condition for the prayer, and this requires more than just our standing before Allah and going through the motion of prayer with our bodies and our tongues. The heart has to be in the prayer along with our tongues and our bodies.
