The Messenger of Allah ﷺ said, "There are three whose adversary I shall be on the Day of Resurrection, and whoever has me as his adversary, I will overcome him on the Day of Resurrection. A man who gave his word in My name and then betrayed it, a man who sold a free person and consumed the price, and a man who hired a worker, took full service from him, but did not pay him his wages."
حدثنا سويد بن سعيد حدثنا يحيى بن سليم عن إسمعيل بن أمية عن سعيد بن أبي سعيد المقبري
قال رسول الله ﷺ ثلاثة أنا خصمهم يوم القيامة ومن كنت خصمه خصمته يوم القيامة رجل أعطى بي ثم غدر ورجل باع حرا فأكل ثمنه ورجل استأجر أجيرا فاستوفى منه ولم يوفه أجره
Bukhari narrated it in the Book of Sales, in the chapter on the sin of one who sells a free person, hadith 2227, from the hadith of Yahya bin Salim, through this route.Yahya was deemed trustworthy by the majority of scholars, except with regard to Ubaydullah bin Umar, so his hadith never falls below the level of hasan. See hadith 2301.
