The words of Shaykh Abu'l Hassan ash-Shadhili~"If you desire to look towards Allah with the eyes of faith and firm belief at all times, then be thankful for His favors, and be content with His Decrees. Whatever favor you have is from Allah. Then, whenever evil touches you, call upon Him. If... you desire it to turn away from you, or yourself to turn away from it, worship Allah lovingly, not bargaining with Him, but knowingly, with due respect and modesty."
