In The Name of Allaah, The Most Merciful The Bestower of Mercy

Imaam Sufyaan Ath-Thawree (rahimahullaah) said: Be mindful of Allaah’s Anger in three affairs: Be mindful of falling short in that which you have been commanded; be mindful that He sees you, whilst you are not pleased with what He has portioned for you (of the dunyah); be mindful that you seek for something from the worldly life and do not find it, so you become angry with your Lord. [Siyar A’laam Nubulaa 7/244]
