proper manner, whilst keeping in mind the relative sunan, etc.

Salah will be an expiation for minor sins but not for major ones, as major sins are not forgiven through salah. (The forgiveness of major sins is through repentance and fulfilling its requirements).^[1]

A way of gaining blessings in livelihood

One of the best ways of gaining blessings in one’s livelihood is for a person to offer salah calmly, with humility, and whilst fulfilling its wājibāt and Sunan actions.^[2]

Offering salah despite a fire

The TābiꜤī, Muslim b. Yasār رَحْمَةُ الـلّٰـهِ عَـلَيْه, offered salah with such focus that he would be completely unaware of what was occurring around him. Once, a fire broke out near him, but he did not even realise this as he was busy offering salah. This continued until the fire was extinguished.^[3]

May Allah Almighty grant us the ability to offer Salah with humility and focus. As for how we can do this and what we must do beforehand, Mawlana Ilyas Attar al-Qadiri  دَامَـتْ بَـرَكَـاتُـهُـمُ الْـعَـالِـيَـهْexplained this in his book: Blessings of Salah.

Sins are a major obstacle to humility

He writes:

If you wish to offer Salah with humility and focus, then you must first avoid sins. Sins are a major obstacle in this path. Humility cannot be attained while remaining persistent in sin.
