 Reference : Riyazussaleheen : Book1, Hadith 181

181. Tamim receptacle Aus Ad-Dari (May Allah be satisfied with him) revealed: The Prophet (PBUH) said, "Promotion Deen is truthfulness". We said: "For whom?'' He answered, "For Allah, His Book, His Messenger and for the heads of the Muslims and their masses". [Muslim 

Discourse: This Hadith focuses on the significance and benefits of general earnestness. Earnestness for Allah here implies that one should have genuine confidence in Him and He ought to be adored with full dedication and truthfulness. Genuineness for the Qur'an implies that one ought to affirm its fact with one's full heart and brain, recount it consistently, follow up on the directives contained in it with fastidious mind and stringently stay away from its confusion. Genuineness of the Prophet (PBUH) implies earnest affirmation of his Prophethood, dedicated submission of his orders and adherence to his Sunnah. The altruism of the Muslim rulers remains here for co-working with them in their legal orders and compliance of their such orders which are liberated from any hint of transgression. In the event that they digress from the Straight Path they ought to be convinced to go to ideals. One ought not rebel against them except if they submit treachery. The altruism of the Muslim masses implies that one should work for the improvement of their life in this world and the Hereafter. They ought to be given the correct direction, actuated to perform great deeds and deflected from shades of malice.
