Did Mu'adh not know Allah's right over the servants?

Question : Mu'adh's statement, may the Messenger of Allah be upon him, I said, "No," in answering the Prophet's (peace and blessings be upon him) question: Did he not know Allah's right over the servants, or did he intend to say that he was in a gathering with the teacher or the Messenger (peace and blessings be upon him) and wanted to ask for more?

Answer : He may have thought that he wanted a right that was not known, just as the Companions did when the Messenger (peace and blessings be upon him) said, "What day is this?" They said, "Allah and His Messenger know best." They thought he would name it by a name other than its name.
