In a narration from the same Companion, the wording is: The Prophet (peace and blessings be upon him) passed by some people who were wrestling with one another. He asked: "What is this?" The people said: "This is so-and-so, the wrestler; whoever comes up against him, this man throws him down." The Prophet (peace and blessings be upon him) said: "Shall I not guide you to one who is stronger than this man? It is the man who is wronged by another man and gains control over his anger; he overcomes himself, overcomes his own devil, and overcomes the devil of his companion as well."
Al-Bazzar recorded both of these narrations with a single chain. Its chain contains Shu'ayb bin Bayan and Imran al-Qattan; Ibn Hibban declared them both thiqah (trustworthy), while others declared them both da'if (weak). The remaining narrators of both narrations are the narrators of the Sahih.
