Imam Ali (a) is reported to have said, “Trust in Allah the Glorified, for indeed He has guaranteed the sufficiency of those who put their trust in Him.”  (Ghurar al-Hikam, Page 1042)
“When we rely on Allah (swt) and know that whatever happens is for the best, then we can think correctly. “You are not what you think you are; but what you think, you are!”
