Rumana

“Had Allah lifted the veil for his slave and shown him how He handles his affairs for him, and how Allah is keener for the benefit of the slave than his own self, his heart would have melted out of love for Allah and would have torn to pieces out of thankfulness to Allah. Therefore if the pains of this world tire you, do not grieve. For it maybe that Allah yearns to hear your voice by way of du'a. So pour out your desires in prostration and forget about it and know that verily Allah does not forget.”
― Ibn Al Qayyim, Unknown Book 8458185
