It is narrated from Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) that he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "Leave what makes you doubt for what does not make you doubt, for good (truth) is tranquillity and evil (falsehood) is doubt and unease." This hadith has a sahih (authentic) chain, but the two Shaykhs did not record it.

It is narrated from Sayyiduna al-Hasan bin Ali (may Allah be pleased with them both) that a man came to the Messenger of Allah (peace and blessings be upon him), and I heard the Messenger of Allah (peace and blessings be upon him) say: "Leave what makes you doubt and take up what does not make you doubt, for evil is doubt and good is tranquillity." Its corroborating report is the hadith of Sayyiduna Abu Umamah al-Bahili (may Allah be pleased with him).

It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that a man asked the Prophet (peace and blessings be upon him): What is faith? He (peace and blessings be upon him) said: "When your good deed pleases you and your bad deed grieves you, then you are a believer." He said: O Messenger of Allah, what is sin? He (peace and blessings be upon him) said: "When something troubles your chest (creates doubt), then leave it."

It is narrated from Sayyiduna Nawwas bin Sim'an al-Ansari (may Allah be pleased with him) that he said: I asked the Prophet (peace and blessings be upon him) about righteousness and sin, and he (peace and blessings be upon him) said: "Righteousness is good character, and sin is what troubles your heart and you dislike that people should come to know of it." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

Amr bin Shu'ayb narrates from his father, and he from his grandfather (Sayyiduna Abdullah bin Amr (may Allah be pleased with them both)), that one night the Messenger of Allah (peace and blessings be upon him) was very restless. It was said to him (peace and blessings be upon him): What has kept you awake? He (peace and blessings be upon him) said: "I found a fallen date and ate it. Then I remembered that we also had some dates of charity, and now I do not know whether that date was from them or from the dates of my household. It is this that kept me awake." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "I do not know whether Tubba' (the king of Yemen) was accursed or not; and I do not know whether Dhu al-Qarnayn was a prophet or not; and I do not know whether the (legal) hadd punishments are an expiation for those who receive them or not." This hadith is sahih (authentic) on the condition of Imam Bukhari and Imam Muslim, but the two Shaykhs did not record it.

It is narrated from Sayyiduna Abdullah bin Umar and Sayyiduna Abdullah bin Abbas (may Allah be pleased with them) that they both used to report from the Messenger of Allah (peace and blessings be upon him): "Whoever buys something and the sale becomes binding for him, he has the option as long as he has not parted from his companion (the seller); if he wishes, he may take it. But once he has parted from him, he no longer has the option (to cancel)." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it with these words.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that in the time of the Prophet (peace and blessings be upon him) a man bought a slave from another man. The slave remained with him for as long as Allah willed; then he returned him because of a defect that he found in him. When the slave was returned, the seller said: O Messenger of Allah, he has been benefiting (earning income) from my slave for all this time. The Prophet (peace and blessings be upon him) said: "The benefit belongs to the one who bears responsibility for loss (that is, the income belongs to the one in whose possession the item was at risk of perishing)."

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that in the time of the Prophet (peace and blessings be upon him) a man bought a slave who had a defect of which he was unaware. He made use of the slave (or earned income from him); then when he learned of the defect, he returned him. Then the two parties took their dispute to the Prophet (peace and blessings be upon him), and the seller said: O Messenger of Allah, he has benefited from him for a long time. The Messenger of Allah (peace and blessings be upon him) said: "The income is in return for the liability (responsibility for loss)." The chain of this hadith is sahih (authentic), but the two Shaykhs did not record it. Ibn Abi Dhi'b has also narrated it in abridged form through Makhlad bin Khufaf from Sayyidah Aishah.

It is narrated from Sayyidah Aishah (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: "Indeed, the benefit (income) is in return for the liability (responsibility for loss)." The wording of the narration of Asim is that the Messenger of Allah (peace and blessings be upon him) ruled that the income is in return for the liability. Sufyan al-Thawri, Ibn al-Mubarak and Yahya bin Sa'id have narrated it from Ibn Abi Dhi'b.
