Sayyiduna Usama bin Zaid (may Allah be pleased with him) narrated from the Messenger of Allah (peace and blessings be upon him), he said: The plague was mentioned before the Prophet (peace and blessings be upon him), so he said: "The plague is a punishment which was sent down, or with it a nation from among the nations before you was punished, and it is some of its remnants. When you hear that the plague has broken out in a land, do not go there, and when it breaks out in the land where you are, do not flee from it." Muhammad bin Munkadir said: I narrated this hadith to Umar bin Abdul Aziz, so he said: 'Aamir bin Sa’d (may Allah have mercy on him) narrated this hadith to me in the same way.'

Usama bin Zaid, may Allah be pleased with him, narrates that the Messenger of Allah, peace and blessings be upon him, said: "Plague is a punishment that was sent upon the people before you or upon the Children of Israel. When plague spreads in a land, do not go there, and when it spreads in a land where you are residing, do not leave from there."

Ibrahim bin Abdullah narrated to me the hadith, he said: Muhammad bin Hafs narrated to us, he said: My father narrated to us from Shaibani, he said: Habib bin Abi Thabit narrated to me from Ibrahim bin Sa’d, he narrated this and then narrated a hadith similar to the previous hadith.

Ibrahim narrated to me the hadith, he said: Umar bin Hafs narrated to us, he said: My father narrated to us, from Shaibani, from Abu Bakr, who said: Umar bin Abdul Aziz narrated to me from Amir bin Sa’d, similar to the previous hadith. All the narrators mention the hadith through Usama bin Zaid (may Allah be pleased with him).

It is narrated from Abdullah bin Abdur Rahman that Amir bin Sa’d narrated a hadith to Umar bin Abdul Aziz (may Allah have mercy on him) when he was the governor of Madinah. Sa’d bin Malik (may Allah be pleased with him) informed him that indeed the Messenger of Allah (peace and blessings be upon him) said:“Whoever eats seven ‘ajwa dates from the area between the two black rocky tracts of Madinah, and begins his day with them, no poison will harm him that day until night.”Amir bin Sa’d was told by Umar bin Abdul Aziz,“O Sa’d! See what you are attributing to the Messenger of Allah (peace and blessings be upon him)!”Sa’d replied,“I testify that I have not attributed any lie to Sa’d bin Malik (may Allah be pleased with him), nor did Sa’d (may Allah be pleased with him) attribute any lie to the Messenger of Allah (peace and blessings be upon him).”Umar bin Abdul Aziz (may Allah have mercy on him) said,“And I testify that the Messenger of Allah (peace and blessings be upon him) did not speak falsely.”
