Ibn Abbas (may Allah be pleased with them both) narrated that the Prophet (peace and blessings be upon him) sent Dihyah al-Kalbi (may Allah be pleased with him) with his letter to the ruler of Busra, so that he would deliver this letter to Caesar, the king of Rome.

Narrated `Abdullah bin `Abbas: Allah's Apostle sent a letter to Khosrau and told his messenger to give it first to the ruler of Bahrain, and tell him to deliver it to Khosrau. When Khosrau had read it, he tore it into pieces. (Az-Zuhri said: I think Ibn Al-Musaiyab said, "Allah's Apostle invoked Allah to tear them (Khosrau and his followers) into pieces."

Narrated Salama bin Al-Akwa`: Allah's Apostle said to a man from the tribe of Al-Aslam, "Proclaim among your people (or the people) on the day of 'Ashura' (tenth of Muharram), 'Whosoever has eaten anything should fast for the rest of the day; and whoever has not eaten anything, should complete his fast.' "

This has been narrated by Malik bin Huwairith, may Allah be pleased with him.

Narrated Ibn `Abbas: When the delegate of `Abd Al-Qais came to Allah's Apostle, he said, "Who are the delegate?" They said, "The delegate are from the tribe of Rabi`a." The Prophet said, "Welcome, O the delegate, and welcome! O people! Neither you will have any disgrace nor will you regret." They said, "O Allah's Apostle! Between you and us there are the infidels of the tribe of Mudar, so please order us to do something good (religious deeds) that by acting on them we may enter Paradise, and that we may inform (our people) whom we have left behind, about it." They also asked (the Prophet) about drinks. He forbade them from four things and ordered them to do four things. He ordered them to believe in Allah, and asked them, "Do you know what is meant by belief in Allah?" They said, "Allah and His Apostle know best." He said, ''To testify that none has the right to be worshipped except Allah, the One, Who has no partners with Him, and that Muhammad is Allah's Apostle; and to offer prayers perfectly and to pay Zakat." (the narrator thinks that fasting in Ramadan is included), "and to give one-fifth of the war booty (to the state)." Then he forbade four (drinking utensils): Ad-Duba', Al-Hantam, Al-Mazaffat and An-Naqir, or probably, Al-Muqaiyar. And then the Prophet said, "Remember all these things by heart and preach it to those whom you have left behind."

Narrated Tauba Al-`Anbari: Ash-'Shu`bi asked me, "Did you notice how Al-Hasan used to narrate Hadiths from the Prophets? I stayed with Ibn `Umar for about two or one-and-half years and I did not hear him narrating any thing from the Prophet except his (Hadith): He (Ibn `Umar) said, "Some of the companions of the Prophet including Sa`d, were going to eat meat, but one of the wives of the Prophet called them, saying, 'It is the neat of a Mastigure.' The people then stopped eating it. On that Allah's Apostle said, 'Carry on eating, for it is lawful.' Or said, 'There is no harm in eating it, but it is not from my meals."
