It is narrated from Sayyiduna Hudhayfah (may Allah be pleased with him) that he said: "After the tents that used to be with the Messenger of Allah (peace and blessings be upon him), there are no tents (settlements) on the face of the earth from whose people Allah Almighty wards off afflictions as much as He wards them off from the people of these tents" - meaning Kufah.
Imam al-Tabarani (may Allah have mercy on him) said: "No one other than Mus'ab bin Sallam (may Allah have mercy on him) narrated these two hadiths from al-Zibriqan (may Allah have mercy on him)."
