Muawiya rarely narrated from the Prophet ﷺ. Yet he would scarcely let a Friday pass without relating these words from the Messenger of Allah ﷺ, saying, "Whoever Allah wishes good for, He grants him understanding of the religion. This wealth is sweet and lush, so whoever takes it by its rightful means will be blessed in it. Beware of excessive praise of one another, for it is slaughter."
كان معاوية قلما يحدث عن النبي ﷺ، قال: فكان قلما يكاد أن يدع يوم الجمعة هؤلاء الكلمات أن يحدث بهن عن رسول الله ﷺ يقول: من يرد الله به خيرا يفقهه في الدين، وإن هذا المال حلو خضر، فمن يأخذه بحقه يبارك له فيه، وإياكم والتمادح، فإنه الذبح.
Ahmad (16846) and Ibn Majah (3743) both narrated it through Shubah, who said, Saad bin Ibrahim told me, from Mabad Juhani, who said, and he mentioned it. The wording is Ahmad's, and Ibn Majah abridged it. Its chain is hasan because of Mabad bin Khalid Juhani, for he is hasan al-hadith. Mabad Juhani was the first to openly promote the belief denying divine decree in Basra, but there is nothing in his hadith that supports his innovation.
