Narrated Mu'adh bin Jabal: While I was riding behind the Prophet ﷺ as a companion rider and there was nothing between me and him except the back of the saddle, he said, "O Mu'adh!" I replied, "Labaik O Allah's Messenger ﷺ! And Sa'daik!" He proceeded for a while and then said, "O Mu'adh!" I said, "Labaik and Sa'daik, O Allah's Messenger ﷺ!" He then proceeded for another while and said, "O Mu'adh bin Jabal!" I replied, "Labaik, O Allah's Messenger ﷺ, and Sa'daik!" He said, "Do you know what is Allah's right on His slaves?" I replied, "Allah and His Apostle know better". He said, "Allah's right on his slaves is that they should worship Him and not worship anything besides Him". He then proceeded for a while, and again said, "O Mu'adh bin Jabal!" I replied".Labaik, O Allah's Messenger ﷺ, and Sa'daik". He said, "Do you know what is (Allah's) slaves' (people's) right on Allah if they did that?" I replied, "Allah and His Apostle know better". He said, "The right of (Allah's) slaves on Allah is that He should not punish them (if they did that).
