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

الْمُؤمِنُ یَحْتاجُ إلى ثَلاثِ خِصالٍ: تَوْفیقٍ مِنَ اللّهِ عَزَّوَجَلَّ، وَ واعِظٍ مِنْ نَفْسِهِ، وَقَبُولٍ مِمَّنْ یَنْصَحُ.

“Every believer needs three qualities: grace from Allah Almighty, a preacher inside himself, and acceptance of the advice of others.”
