In The Name of Allaah, The Most Merciful The Bestower of Mercy
Imaam Sadi (rahimahullaah) said:
Ponder upon the stories of some of the distinguished people of (piety) and that which they were upon of a life of goodness.
And whether they were rich or poor, in hardship or ease, or whether their situation changed from one state to another, indeed you still found them to be the most well behaved amongst the people, the most relaxed at heart and the most delighted; rather you will find one amongst them in a state of insignificance and poverty, whilst being pleased and contented and not angry with Allaah and the creation. This is a blessing from Allaah which He bestows on whomsoever He pleases, and He is the Possessor of all blessings.
As for the worshippers of the worldly life-those who are have submitted to its glitter-; they do not care how they gather wealth, whether through permissible or impermissible means. They do not mind to (utter) false and evil speech against the righteous slaves of Allaah, (whilst being) heedless, seeking to raise themselves and disseminating their falsehood and rumours for the sake of their merchandises and to fulfil their lowly desires. However, your Lord knows about them, and He is Ever Watchful over them.
