Habib bin Abi Thabit

Narrated Habib bin Abi Thabit: I went to Abu Wail to ask him (about those who had rebelled against `Ali). On that Abu Wail said, "We were at Siffin (a city on the bank of the Euphrates, the place where me battle took place between `Ali and Muawiya) A man said, "Will you be on the side of those who are called to consult Allah's Book (to settle the dispute)?" `Ali said, 'Yes (I agree that we should settle the matter in the light of the Qur'an)." ' Some people objected to `Ali's agreement and wanted to fight. On that Sahl bin Hunaif said, 'Blame yourselves! I remember how, on the day of Al-Hudaibiya (i.e. the peace treaty between the Prophet (ﷺ) and the Quraish pagans), if we had been allowed to choose fighting, we would have fought (the pagans). At that time `Umar came (to the Prophet) and said, "Aren't we on the right (path) and they (pagans) in the wrong? Won't our killed persons go to Paradise, and theirs in the Fire?" The Prophet replied, "Yes." `Umar further said, "Then why should we let our religion be degraded and return before Allah has settled the matter between us?" The Prophet (ﷺ) said, "O the son of Al-Khattab! No doubt, I am Allah's Messenger (ﷺ) and Allah will never neglect me." So `Umar left the place angrily and he was so impatient that he went to Abu Bakr and said, "O Abu Bakr! Aren't we on the right (path) and they (pagans) on the wrong?" Abu Bakr said, "O the son of Al-Khattab! He is Allah's Messenger (ﷺ), and Allah will never neglect him." Then Sura Al-Fath (The Victory) was revealed."

Shu'ba reported from Habib:While we were in Medina we heard of plague having broken out in Kufa. 'Ata b. Yasir and others said to me that Allah's Messenger (ﷺ) had said. If you are in a land where it (this scourge) has broken out, don't get out of it, and if you were to know that it had broken (in another land, then don't enter it. I said to him: From whom (did you hear it)? They said: 'Amir b. Sa'd has narrated it. So I came to him. They said that he was not present there. So I met his brother Ibrahim b. Sa'd and asked him. He said: I bear testimony to the fact that Usama narrated it to Sa'd saying: I heard Allah's Messenger (ﷺ) as saying that it is a God-sent punishment from the calamity or from the remnant of the calamity with which people were afflicted before you. So when it is in a land and you are there, don't get out of it, and if (this news reaches you) that it has broken out in a land, then don't enter therein. Habib said: I said to Ibrahim: Did you hear Usama narrating it to Sa'd and he was not denying it. He said: Yes
