I was a companion rider of the Prophet ﷺ on a donkey called 'Ufair. The Prophet ﷺ asked, "O Muʿadh! Do you know what Allah's right on His slaves is, and what the right of His slaves on Him is?" I replied, "Allah and His Apostle know better." He said, "Allah's right on His slaves is that they should worship Him (Alone) and should not worship any besides Him. And slave's right on Allah is that He should not punish him who worships none besides Him." I said, "O Messenger of Allah ﷺ! Should I not inform the people of this good news?" He said, "Do not inform them of it, lest they should depend on it (absolutely). (Using translation from Bukhārī 2856)   

كُنْتُ رَدِيفَ النَّبِيِّ ﷺ فَقَالَ «أَتَدْرِي مَا حَقُّ اللهِ عَلَى الْعِبَادِ وَمَا حَقُّ الْعِبَادِ عَلَى اللهِ؟» قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ «حَقُّ اللهِ عَلَى الْعِبَادِ أَنْ لَا يُشْرِكُوا بِهِ شَيْئًا وَإِنَّ حَقَّ الْعِبَادِ عَلَى اللهِ أَنْ لَا يُعَذِّبَ مَنْ فَعَلَ ذَلِكَ مِنْهُمْ» قُلْتُ يَا رَسُولَ اللهِ أَفَلَا أُبَشِّرُ النَّاسَ؟ قَالَ «دَعْهُمْ لَا يَتَّكِلُوا»
