He told me, from one who heard Farwah ibn Musayk, who said: I said, "O Messenger of Allah, may Allah bless him and grant him peace, we have land called the land of Abyan; it is the land of our cultivation and our sustenance, and it is pestilential" — or he said, "its pestilence is severe." The Prophet, may Allah bless him and grant him peace, said: "Leave it alone, for from proximity to disease comes destruction." (1)

3924 — Al-Hasan ibn Yahya al-Azdi narrated to us, Bishr ibn Umar narrated to us, from Ikrimah ibn Ammar, from Ishaq ibn Abdullah ibn Abi Talhah, from Anas ibn Malik, who said: A man said, "O Messenger of Allah, we were in a dwelling where our numbers were many and our wealth was abundant, then we moved to another dwelling where our numbers became few and our wealth diminished." The Messenger of Allah, may Allah bless him and grant him peace, said: "Leave it, for it is blameworthy." (2)

--------------------------------------------
(1) Its chain of transmission is weak, due to the anonymity of the man who heard Farwah ibn Musayk, and the unknown status of Yahya ibn Abdullah ibn Bahir.
It is found in the "Musannaf" of Abd al-Razzaq (20163), and through him Ahmad (15742), and al-Bukhari in "al-Tarikh al-Kabir," 8/286, and Ibrahim al-Harbi in "Gharib al-Hadith" 2/365, and al-Bayhaqi in "al-Sunan al-Kubra," 9/347, and in "Shu'ab al-Iman" (1365), and al-Mizzi in the biography of Farwah ibn Musayk from "Tahdhib al-Kamal" 23/177.
It was also narrated by Ibn Qani' in "Mu'jam al-Sahabah" 2/337, and Abu al-Shaykh in "al-Amthal" (305) via the path of Abdullah ibn Mu'adh al-San'ani, from Ma'mar, from Yahya ibn Abdullah, from Farwah, without mentioning the anonymous narrator.
Al-Khattabi said: Al-Qutaybi (i.e., Ibn Qutaybah) mentioned this hadith in his book and explained it. He said: "Al-qaraf" means proximity to pestilence and proximity to disease.

(2) Its chain of transmission is weak; Ikrimah ibn Ammar was alone in this chain, and the sole narration of someone like him is not acceptable. For this reason, al-Bukhari said in "al-Adab al-Mufrad": "There is concern in its chain." Malik narrated it from Yahya ibn Sa'id al-Ansari as a mursal report, and al-Zuhri narrated it from Abdullah ibn al-Harith ibn Nawfal, from Abdullah ibn Shaddad, also as a mursal report. =
