Sayyiduna Abdullah bin Amr (may Allah be pleased with him) reports this saying of the Prophet (peace and blessings be upon him): "I have been given the strength of forty men in grip and in intimacy." (Allamah al-Haythami says:) I say: After this he mentioned the whole hadith; this long hadith has already preceded in the Book of Marriage. Its chain contains al-Mughirah bin Qays, who is da'if (weak).
Sayyiduna Anas (may Allah be pleased with him) narrates: "I have been given superiority over other people in four respects: generosity, bravery, the capacity for frequent intimacy, and a strong grip."
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and the narrators of its chain have been declared trustworthy.
Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "I have been given superiority over the other Prophets in two respects: my devil was a disbeliever, and Allah Almighty helped me against him until he submitted (became Muslim)." The narrator of the hadith says: I have forgotten the other thing.
Al-Bazzar recorded it; its chain contains Ibrahim bin Sirmah, who is da'if (weak). Some hadiths on this subject, that the Prophet (peace and blessings be upon him) was protected from the "qarin" (the companion devil), have already preceded.
