Do not grieve

"Had Allaah lifted the veil for his slave and shown him how He handles his affairs for him, and how Allaah is more keen for the benefit of the slave than his own self, his heart would have melted out of the love for Allaah and would have been torn to pieces out of thankfulness to Allaah. Therefore if the pains of this world tire you do not grieve. For it may be that Allaah wishes to hear your voice by way of du'ah. So pour out your desires in prostration and forget about it and know; that verily Allaah does not forget it."

- Ibn al-Qayyim (rahimahUllaah)
