ـ رسولُ اللهِ (صَلَّيَ اللهُ عَلَيهِ وَ آلِهِ) : ثَلاثٌ مَن لَم يَكُن فِيه لِمَ يَتِمَّ لَهُ عَمَلٌ : وَرَعٌ يَحجُزُهُ عَن مَعاصِي اللّه‏ِ ، وخُلُقٌ يُدارِي بِهِ النّاسَ ، وحِلْمٌ يَرُدُّ بِهِ جَهلَ الجاهِلِ. 
‪The Prophet (SAWA) said, ‘There are three things that if are not present with someone then their actions are incomplete: piety preventing one from disobeying Allah, a character through which one is amicable towards people, and clemency with which to deal with the rashness of the ignorant.’[al-Kafi, v. 2, p. 116, no. 1]
