﴿ يُثَبِّتُ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ بِٱلْقَوْلِ ٱلثَّابِتِ فِى ٱلْحَيَوٰةِ ٱلدُّنْيَا وَفِى ٱلْءَاخِرَةِ ۖ وَيُضِلُّ ٱللَّهُ ٱلظَّٰلِمِينَ ۚ وَيَفْعَلُ ٱللَّهُ مَا يَشَآءُ ﴾

“[Thus,] God grants firmness unto those who have attained to faith through the word that is unshakably true in the life of this world as well as in the life to come; but the wrongdoers He lets go astray: for God does whatever He wills.”

Being steadfast in the world means persevering in righteousness and doing good deeds at every turn in one’s life. Being steadfast in the Hereafter means having been successful at the time of questions and answers in the grave. Man is at every moment in the position of being put to the test. He faces different types of favourable and unfavourable events. On these occasions, only those who have grown ‘the tree of faith’ inside themselves behave in a correct and godly way. In the prevailing circumstances, they manifest the most appropriate reaction expected of them according to the will of God. In contrast to this, the man whose personality has grown like a wild bush evinces bitterness at every event; on every occasion he proves to be a thorn and emits a bad smell. When these two types of person are tested finally at the stage of the grave, the one who proves himself to be the ‘good tree’ will be ushered into the Garden of Paradise. And the one who proves to be the ‘evil tree’ will receive the appropriate punishment of being uprooted from this world in order to be thrown as fuel into the fire of Hell.
