Imam Hasan al-Mujtaba (AS)
منِ اِتَّكَلَ عَلَى حُسْنِ اَلاِخْتِيَارِ مِنَ اَللَّهِ لَمْ يَتَمَنَّ أَنَّهُ فِي غَيْرِ اَلْحَالِ اَلَّتِي اِخْتَارَهَا اَللَّهُ لَهُ
He who trusts whatever Allah has chosen for him to be good, will never wish to be in any situation other than what Allah has chosen for him to be in.
Bihar al-Anwar, v 75, p 106
