The Prophet (SAWA) said, ‘The men of knowledge will all be ruined except those who acted [upon their knowledge], and those who act will all be ruined except for the sincere ones from among them, and the sincere ones are significant indeed.
رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : العُلَماءُ كُلُّهُم هَلْكى إلّا العامِلينَ ، والعامِلونَ كُلُّهُم هَلْكى إلّا المُخْلِصينَ، والمُخْلِصونَ على خَطَرٍ.
