We need to grab this golden opportunity to wash away our sins of the past, present and future, with the aid of dhikr, salah, zakat, saum and hajj.
The humility expressed by a believer in his prayers via prostration is ultimate, expressing to the creator, that no one is more supreme in the eyes of this believer. Allah, the Almighty, the most Forgiving has expressed to His creations that He is keenly listening to the pleas of those who are searching for Him in their prayers and prostrations.
The salah needs to be filled with our heart, mind and soul, being fearful of standing in front of Allah, while humbly praising Him and aiming for jannah in the hereafter, in sha Allah. The khushu and khudu, the humility, the devotion, the submissiveness, the humbleness of our limbs, the alertness of our body parts, these are the required elements of a salah which Allah almighty will accept in the akhirah. The true essence and spirit of salah revolves around the presence of khushu and khudu, meaning inward and outward submission and devotion respectively, praising Allah and communicating with Him with our deepest interest and love. The heart remaining free of any worldly worries and tensions while our body exhibits submission of even the tiniest body part.
A momin, when at salah, tries his best to gain an eternal connection with his Supreme Creator. This bonding of the creator and His creation is a desired state longed by a believer, for maintaining a sense of acceptance that he fears Allah and also accepts that He, undoubtedly is the most magnificent, the caretaker of us all. A sense of humility and calmness covers you while you stand in front of your Allah, conversing with him, bonding with him, establishing the soul of your prayers, reminding yourself of your insignificance and His magnificence.
