Tamim ad-Dari (RAA) narrated that the Messenger of Allah (ﷺ) said:

“The religion is Nasihah.” the people said, ‘To whom should it be directed?’ He replied, “To Allah, His Book, His Messenger (ﷺ), to the leaders of the Muslims and to the common folk of the Muslims.” Related by Muslim.

ثَلَاثًا.‏ قُلْنَا: لِمَنْ يَا رَسُولَ اَللَّهِ? قَالَ:

لِلَّهِ وَلِكِتَابِهِ وَلِرَسُولِهِ وَلِأَئِمَّةِ اَلْمُسْلِمِينَ وَعَامَّتِهِمْ } أَخْرَجَهُ مُسْلِمٌ .‏ [1]‏ .‏
