It is narrated from Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever commits a sin that carries a hadd (prescribed punishment), and Allah Almighty hastens its penalty for him in this world (in the form of the punishment), then Allah is far too just to repeat the punishment upon His servant in the Hereafter. And whoever commits a sin that carries a hadd, but Allah Almighty conceals it for him (in this world) and pardons him, then Allah is far too generous to go back on something He has already pardoned." This hadith has a sahih chain, but they (Imam Bukhari and Muslim) did not record it, although both of them used the narration of Abu Juhayfah from Ali bin Abi Talib as evidence, and they also agreed on the narration of Abu Ishaq; moreover, both of them used al-Hajjaj bin Muhammad as evidence, while Imam Muslim also used Yunus bin Abi Ishaq as evidence.

Iyas bin Salamah narrates from his father (Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him)) that he was with the Messenger of Allah (peace and blessings be upon him) when a man came to him (peace and blessings be upon him), leading a pregnant mare of his, with a filly of hers following behind her. The man asked: Who are you? He (peace and blessings be upon him) said: "I am a Prophet." He asked: What is a Prophet? He (peace and blessings be upon him) said: "The Messenger of Allah." He asked: When will the Hour be established? The Messenger of Allah (peace and blessings be upon him) said: "(It is of) the unseen, and none knows the unseen except Allah." He said: Show me your sword. So the Prophet (peace and blessings be upon him) gave him his sword; the man brandished it (in the air) and then returned it to him (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: "Know that you would not have been able to do what you intended (that is, to kill)." The narrator says: The man had already said beforehand: I will go to him and ask him about these matters. This hadith is sahih, but they did not narrate it, although both of them are agreed on using Iyas bin Salamah from his father as evidence, and Imam Muslim, using this very chain as evidence, narrated several hadiths from Ahmad bin Yusuf.
