Hawzah News Agency – Imam al-Kazim peace be upon him says:

إذا مَرَّ بكَ‏ أمرانِ لا تَدري أيُّهُما خَيرٌ وأصوَبُ، فانظُرْ أيُّهُما أقرَبُ إلى‏ هواكَ فخالِفْهُ؛ فإنَّ كَثيرَ الصَّوابِ في مُخالَفَةِ هَواكَ.

'When two things come your way and you do not know which one is good and correct, then look at which one of them is closer to your desire and then oppose it, for most good is found in opposing your desires.'
