" I pledged to the Prophet to establish the Salat, give the Zakat, and to give sincere advice to every Muslim."  

بَايَعْتُ رَسُولَ اللَّهِ ﷺ عَلَى إِقَامِ الصَّلاَةِ وَإِيتَاءِ الزَّكَاةِ وَالنُّصْحِ لِكُلِّ مُسْلِمٍ قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ  

the Messenger of Allah said: "The religion is An-Nasihah" three times. They said: "O Messenger of Allah! For Whom?" He said : "To Allah , His books, the A'immah of the Muslims, and their average people."  

قَالَ رَسُولُ اللَّهِ ﷺ الدِّينُ النَّصِيحَةُ ثَلاَثَ مِرَارٍ قَالُوا يَا رَسُولَ اللَّهِ لِمَنْ قَالَ لِلَّهِ وَلِكِتَابِهِ وَلأَئِمَّةِ الْمُسْلِمِينَ وَعَامَّتِهِمْ
