The worshipper is the one who seeks to master his nafs and not be enslaved by it. He is seeking to make it subservient to Allah, so he can be successful in this life and the hereafter.
The Prophet Muhammad ﷺ said: There is a piece of flesh in the body if it becomes good (reformed) the whole body becomes good but if it gets spoilt the whole body gets spoilt and that is the heart.
The worshipper knows that appreciation and gratitude has no limits, as the favours and blessings of Allah are uncountable.
The Prophet Muhammad ﷺ said: “Wondrous are the believer’s affairs. For him there is good in all his affairs, and this is so only for the believer. When something pleasing happens to him, he is grateful, and that is good for him; and when something displeasing happens to him, he is enduring (ṣabr), and that is good for him.” ( Muslim )
Some of the salaf have mentioned that Ṣabr, patience is one of half of faith, the other is Shukr, gratitude.
