It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“Fighting with a Muslim is disbelief, and abusing him is wickedness, and it is not permissible for any Muslim to cut off relations with his brother for more than three days.”

It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“The greatest offender among the Muslims is the one who asked about something and tried to find out matters that were unpleasant, to the extent that, as a result of his question, the ruling of prohibition regarding that thing was revealed.”

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that I heard the Prophet (peace and blessings of Allah be upon him) say:“Whoever wishes to humiliate the Quraysh, Allah will humiliate him.”

It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that once the Prophet (peace and blessings of Allah be upon him) gave wealth and property to some people, but did not give anything to one man among them. Sayyiduna Sa’d (may Allah be pleased with him) said: O Messenger of Allah! You gave to so-and-so and so-and-so, but you did not give anything to this person, even though he is a firm believer. The Prophet (peace and blessings of Allah be upon him) said:“Is he not a Muslim?”This question and answer happened three times. Then the Prophet (peace and blessings of Allah be upon him) said:“I give to some people and leave those who are more beloved to me, and I do not give them anything out of fear and concern that they might be dragged on their faces and thrown into Hell.”

It is narrated from Sayyiduna Sa'd (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) ordered the killing of the lizard, and he (peace and blessings be upon him) called it "Fuwaiysiqa" (which is the diminutive form of "Fasiq" - evildoer).

(Marfu‘ hadith) ‘Abd al-Razzaq narrated to us, Ma‘mar narrated to us, from al-Zuhri, from ‘Amir ibn Sa‘d ibn Abi Waqqas, from his father, who said: I was with the Messenger of Allah, peace and blessings be upon him, in the Farewell Pilgrimage, and I became ill with an illness that brought me close to death. The Messenger of Allah, peace and blessings be upon him, visited me, and I said: O Messenger of Allah, I have much wealth and no one will inherit from me except my daughter. Should I bequeath two-thirds of my wealth? He said: "No." I said: Half of my wealth? He said: "No." I said: Then a third of my wealth? He said: "A third, and a third is much. Indeed, O Sa‘d, to leave your heirs wealthy is better for you than to leave them poor, begging from people. Indeed, O Sa‘d, you will not spend anything seeking thereby the Face of Allah, the Exalted, except that you will be rewarded for it, even the morsel you put in your wife's mouth." He said: I said: O Messenger of Allah, will I be left behind after my companions? He said: "You will not be left behind and do a deed seeking thereby the Face of Allah except that you will be increased by it in degree and elevation. And perhaps you will be left behind so that Allah will benefit some people by you and harm others by you. O Allah, complete the migration of my companions and do not turn them back on their heels, but the unfortunate one is Sa‘d ibn Khawlah." The Messenger of Allah, peace and blessings be upon him, grieved for him, and he had died in Mecca.

It is narrated from Sayyiduna Sa'd bin Abi Waqqas (may Allah be pleased with him) that Sayyiduna Uthman bin Maz'un (may Allah be pleased with him) wished to adopt seclusion, but the Prophet (peace and blessings of Allah be upon him) did not permit him to do so. If the Prophet (peace and blessings of Allah be upon him) had permitted him in this matter, then we too would have at least castrated ourselves.

It is narrated from Sayyiduna Sa’d (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“Every prophet has certainly described the characteristics of the Dajjal to his nation, but I will tell you a characteristic about him which no prophet before me has mentioned. Remember! The Dajjal will be one-eyed (and will claim lordship), whereas Allah is not one-eyed.”

It is narrated from Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him) that once the plague was mentioned in the presence of the Prophet (peace and blessings be upon him). The Prophet (peace and blessings be upon him) said:“It is a punishment that was sent upon the nations before you. Therefore, if you hear of its outbreak in a land, do not go there, and if it breaks out in a land where you are, do not leave from there.”

Ibn Muammar says that once ‘Amir bin Sa’d narrated this hadith to ‘Umar bin ‘Abdul Aziz (may Allah have mercy on him)—while he was the governor of Madinah—from his father, Sayyiduna Sa’d bin Abi Waqqas (may Allah be pleased with him), that the Messenger of Allah (peace and blessings be upon him) said:“Whoever in the morning, on an empty stomach, eats seven ‘ajwah dates from anywhere between the two sides of Madinah, nothing will harm him that day until evening.”The narrator thinks that he also said:“And if he eats them in the evening, nothing will harm him until morning.”‘Umar bin ‘Abdul Aziz (may Allah have mercy on him) said:“Amir! Think carefully about what hadith you are narrating from the Prophet (peace and blessings be upon him)!”He said:“I bear witness that I am not lying about Sayyiduna Sa’d (may Allah be pleased with him), and that Sayyiduna Sa’d (may Allah be pleased with him) did not lie about the Prophet (peace and blessings be upon him).”
