It is reported on the authority of Ibn 'Abbas that Mu'adh said: The Messenger of Allah (ﷺ) sent me (as a governor of Yemen) and (at the time of departure) instructed me thus: You will soon find yourself in a community one among the people of the Book, so first call them to testify that there is no god but Allah, that I (Muhammad) am the messenger of Allah, and if they accept this, then tell them Allah has enjoined upon them five prayers during the day and the night and if they accept it, then tell them that Allah has made Zakat obligatory for them that it should be collected from the rich and distributed among the poor, and if they agree to it don't pick up (as a share of Zakat) the best of their wealths. Beware of the supplication of the oppressed for there is no barrier between him and Allah.

The above hadith has been mentioned with a different chain with a slightly different wording at the beginning, then follows the same.

It is narrated on the authority of Ibn 'Abbas that when the Messenger of Allah (ﷺ) sent Mu'adh towards Yemen (as governor) he said to him: Verily you would reach a community of the people of the Book, the very first thing to which you should call them is the worship of Allah, may His Glory be Magnificent, and when they become fully aware of Allah, instruct them that He has enjoined five prayers on them during the day and the night, and when the begin observing it, then instruct them that verily Allah has made Zakat obligatory for them which would be collected from the wealthy amongst them and distributed to their needy ones, and when they submit to it, then collect it from them and avoid (the temptation) of selecting the best (items) of their riches.

Ibn 'Abbas said: We used to know that Allah's Messenger (ﷺ) had finished his prayer when we heard the takbir (Allah-O-Akbar).

Ibn 'Abbas reported: We knew the finishing of the prayer of the Messenger of Allah (ﷺ) through takbir. 'Amr (b. Dinar) said: I made a mention of it to Abu Mas'ud. hue he rejected it and said: I never narrated it to you. 'Amr said: He did narrate it before this.

Ibn 'Abbas reported: Dhikr (mentioning the name of Allah) in a loud voice after obligatory prayers was (a common practice) during the lifetime of the Apostle of Allah (ﷺ) ; and when I heard that I came to knew that they (the people) had finished the prayer.

Ibn 'Abbas narrated from al-Fadl bin Abbas (RA) who sat behind Allah's Messenger (ﷺ) that he (the Holy Prophet) said to the people on the evening of 'Arafa and on the morning to the gathering of people (at Muzdalifa) as they were pushing on to proceed slowly. And he himself drove his she-camel with restraint until he entered Muhassir (it is a place in Mina), and further told them to take up pebbles which were to be thrown at Jamra. And Allah's Messenger (ﷺ) continued pronouncing Talbiya till he stoned the Jamra. This hadith has been narrated on the authority of Abd Zubair with the same chain of transmitters but with this variation that in the hadith no mention is made of (this) that Allah's Messenger (ﷺ) continued pronouncing Talbiya till he stoned the Jamra, and he made this addition in his hadith: "The Apostle (ﷺ) pointed with his hand how a person should catch hold of pebbles (in order to throw them)."

Ibn 'Abbas (RA) reported: I heard Allah's Messenger (ﷺ) delivering a sermon and making this observation: "No person should be alone with a woman except when there is a Mahram with her, and the woman should not undertake journey except with a Mahram." A person stood up and said: Allah's Messenger, my wife has set out for pilgrimage, whereas I am enlisted to fight in such and such battle, whereupon he said: "You go and perform Hajj with your wife."
