While I was riding behind the Prophet ﷺ and between me and him and between me and him there was only the back of the saddle, he said, "0 Muʿadh!" I replied, "Labbaik, 0 Messenger of Allah ﷺ, and Saʿdaik!" he said, "Do you know what is Allah's right upon his slave?" I said, "Allah and His Apostle know best" He said "Allah's right upon his slaves is that they should worship Him alone and not worship anything else besides Him." Then he proceeded for a while and then said, "O Muʿadh bin Jabal!" I replied, "Labbaik, O Messenger of Allah ﷺ:, Saʿdaik!' He said, "Do you know what is the right of the slaves upon Allah if they do that?" I replied, "Allah and His Apostle know best." He said, "The right of the slaves upon Allah is that He will not punish them (if they do that). (Using translation from Bukhārī 5967)   

كُنْتُ رَدِيفَ النَّبِيِّ ﷺ وَمَا بَيْنِي وَبَيْنَهُ إِلَّا آخِرَةُ الرَّحْلِ فَقَالَ «يَا مُعَاذُ» فَقُلْتُ لَبَّيْكَ يَا رَسُولَ اللهِ وَسَعْدَيْكَ قَالَ «أَتَدْرِي مَا حَقُّ اللهِ عَلَى الْعِبَادِ؟» قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ «حَقُّ اللهِ عَلَى الْعِبَادِ أَنْ يَعْبُدُوهُ وَلَا يُشْرِكُوا بِهِ شَيْئًا» ثُمَّ قَالَ «يَا مُعَاذُ بْنَ جَبَلٍ» قُلْتُ لَبَّيْكَ يَا رَسُولَ اللهِ وَسَعْدَيْكَ قَالَ «هَلْ تَدْرِي مَا حَقُّ الْعِبَادِ عَلَى اللهِ إِذَا فَعَلُوا ذَلِكَ؟» قُلْتُ اللهُ وَرَسُولُهُ أَعْلَمُ قَالَ «حَقَّهُمْ عَلَيْهِ أَنْ لَا يُعَذِّبَهُمْ»  

[Machine] I took a dose that burned my hand, so my mother took me to a man sitting in the cemetery. She said to him, "O Messenger of Allah, help and heal." Then she brought me closer to him, and he began to spit and speak with words that I don't know what they are. So I asked my mother later what he was saying. She said he was saying, "Remove the affliction, O Lord of the people, heal, for there is no healer except You."  

تَنَاوَلْتُ قِدْرًا كَانَتْ لِي فَاحْتَرَقَتْ يَدَيَّ فَانْطَلَقَتْ بِي أُمِّي إِلَى رَجُلٍ جَالِسٍ فِي الْجَبَّانَةِ فَقَالَتْ لَهُ يَا رَسُولَ اللهِ قَالَ «لَبَّيْكِ وَسَعْدَيْكِ» ثُمَّ أَدْنَتْنِي مِنْهُ فَجَعَلَ يَتْفِلُ وَيَتَكَلَّمُ بِكَلَامٍ مَا أَدْرِي مَا هُوَ فَسَأَلْتُ أُمِّي بَعْدَ ذَلِكَ مَا كَانَ يَقُولُ قَالَتْ كَانَ يَقُولُ «أَذْهِبِ الْبَاسَ رَبَّ النَّاسِ اشْفِ أَنْتَ الشَّافِي لَا شَافِيَ إِلَّا أَنْتَ»
