Muaz said, "I was riding behind the Prophet ﷺ on a red camel when he said, 'Muaz.'I answered, 'At your service.'He asked, 'Do you know what Allah's right over His servants is?'I said, 'Allah and His Messenger know best.'He asked this three times, and I gave that same answer three times. Then he said, 'His right is that they worship Him and associate nothing with Him.'Then he asked, 'Do you know what the servants' right over Allah is, if they do that?'I said, 'Allah and His Messenger know best.'He asked this three times, and I gave that same answer three times. Then he said, 'Their right over Him, if they do that, is that He forgive them and admit them into Paradise.'"He said that a donkey was brought to the Messenger of Allah ﷺ with a saddle pad fastened on it, except that Hasan combined the two chains of transmission in his version of the hadith.
حدثنا عفان وحسن قالا ثنا حماد عن عطاء بن السائب عن أبي رزين عن معاذ بن جبل مثله غير أنه قال أتي رسول الله ﷺ بحمار قد شد عليه بردعة إلا أن حسنا جمع الإسنادين في حديثه
Its isnad is sahih. Abu Razin is al-Asadi, whose name is Masud bin Malik, and he is one of the eminent, trustworthy Successors, as already mentioned. The hadith is like the one before it.
