عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ الدِّينُ النَّصِيحَةُ ثَلَاثَ مَرَّاتٍ قَالَ قِيلَ يَا رَسُولَ اللَّهِ لِمَنْ قَالَ لِلَّهِ وَلِكِتَابِهِ وَلِأَئِمَّةِ الْمُسْلِمِينَ
Syedna Abu Hurairah, may Allah be pleased with him, narrates that the Messenger of Allah, peace and blessings be upon him, said: Religion is sincerity. He said it three times. Someone asked: O Messenger of Allah! For whom? He, peace and blessings be upon him, said: For Allah Almighty, His Book, and for the leaders of the Muslims.
