Ahmad transmitted it (5/382), and its chain of transmission is authentic according to the criteria of both al-Bukhari and Muslim. Al-Bukhari also transmitted it (6314), but without mentioning “the right hand,” as did al-Tirmidhi (3395), who said: “A good, authentic hadith.” This additional wording escaped al-Hafiz’s notice, so he did not attribute it to Ahmad!

This is an important point in this issue, one that many young people zealous for the implementation of Islam overlook; and for that reason, they often
