وَعَنْ أَبِي سَعِيدٍ
قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «مَا بَعَثَ اللَّهُ مِنْ نَبِيٍّ وَلَا اسْتَخْلَفَ مِنْ خَلِيفَةٍ إِلَّا كَانَتْ لَهُ بِطَانَتَانِ: بِطَانَةٌ تَأْمُرُهُ بِالْمَعْرُوفِ وَتَحُضُّهُ عَلَيْهِ وَبِطَانَةٌ تَأْمُرُهُ بِالشَّرِّ وَتَحُضُّهُ عَلَيْهِ وَالْمَعْصُومُ مَنْ عصمَه اللَّهُ»
The Messenger of Allah (sallallahu alayhi wa sallam) said:, “No prophet is sent by God and no caliph succeeds another without having two close associates, one who commands and urges him to do what is reputable and one who commands and urges him to do what is evil. The one who is protected is he whom God protects.”
