Mu'awiya ibn Qurra said, "My father told me, 'If you sit in a gathering expecting good to come from, but then something occurs which makes you leave, say, 'Peace be upon you,' and you will share in any good that they obtain in that gathering. There are no people who sit in a gathering and then split up without Allah having been mentioned, but that it is as if they were leaving the corpse of a donkey.'"

'Umar ibn 'Abdu'l-'Aziz asked Abu Bakr ibn Abi Hathama, "Why did Abu Bakr write, 'From Abu Bakr, the Khalifa (Successor) of the Messenger of Allah' and then 'Umar wrote after him, 'From 'Umar ibn al-Khattab, the khalifa (successor) of Abu Bakr'? Who was the first to write 'the Amir al-Mu'minin'?" He replied, "My grandmother, ash-Shifa', related to me, and she was one of the first to write 'the Amir al-Mu'minin'?" He said, "My grandfather, ash-Shifa' related to me, (and she was one of the first Muhajirun and when 'Umar ibn al-Khattab entered the market, he visited her), saying, ''Umar ibn al-Khattab wrote to the governor of Iraq requesting him to send him two trustworthy noble men so that he could question them about Iraq and its people. He sent him a master of Iraq, Labid ibn Rabi'a and also 'Adi ibn Hatim, and they came to Madina. They made their camels kneel in the courtyard of the mosque, entered it and found 'Amr ibn al-'As. They said to him, ''Amr, ask permission for us to visit the Amir al-Mu'minin, 'Umar.' 'Amr got up and went to 'Umar. He said, 'Peace be upon you, Amir al-Mu'minin.' 'Umar said to him, 'Ibn al-'As, what made you use this name? You have deviated from what you normally say.' He said, 'Yes, Labid ibn Rabi'a and 'Adi ibn Hatim came and said to me, "Ask permission for us to visit the Amir al-Mu'minin." I said, "You two, by Allah, have hit upon the correct name. He is the amir and we are the believers."' The title originated on that day."

'Ubaydullah ibn 'Abdullah said, "Mu'awiya went on his first hajj when he was the khalifa and 'Uthman ibn Hanif al-Ansari came to him and said, 'Peace be upon you, Amir, and the mercy of Allah.' The people of Syria objected to that and said, 'Who is this hypocrite who shortens the greeting of the Amir al-Mu'minin!' 'Uthman made his camel kneel and said, 'Amir al-Mu'minin! These men object to something which you know better than them. By Allah, I used to this greeting for Abu Bakr, 'Umar, and 'Uthman, and none of them objected to it.' Mu'awiya said to those of the people of Syria who had spoken, 'Take it easy! It was partly as he stated. But when the civil war engaged the people of Syria, they said, "Do not shorten the greeting of our khalifa in our presence (i.e. from Amir al-Mu'minin to Amir)." People of Madina, I will treat you as friends even though you use 'Amir" for a zakat collector.'"

Ziyad ibn 'Ubayd (ar-Ru'ayni) said, "We went to Ruwayfa', the Amir of Antabulis. A man came and greeted him, saying, 'Peace be upon the Amir.' From 'Abda, he said, 'Peace be upon the Amir.' Ruwayfa' said to him, 'If you had greeted us, we would have returned the greeting. But you greeted Maslama ibn Mukhallad (Maslama was in charge of Egypt). Go to him and he will return your greeting.'"

'Umar said to 'Adi ibn Hatim, "May Allah preserve you from recognition."

Mu'awiya ibn Qurra said that his father said to him, "My son, when a man passes by you and says, 'Peace be upon you (plural).' Do not say, 'And on you (singular)' as if you were singling out that greeting out for him alone. Rather say, 'Peace be upon you (plural).'"

Asma' was heard to say that the Prophet, may Allah bless him and grant him peace, passed by a group of women sitting down in the mosque. He said to the salam with his hand and said, "Beware of the ingratitude of those with blessings. Beware of the ingratitude of those with blessings." One of them said, "We seek refuge with Prophet, Prophet of Allah, from ingratitude for the blessings of Allah." He said, "Yes. One of you women might have been without a husband for a long time (and then Allah provides her with one) and she becomes angry and says, 'By Allah, I have never seen a hour of good from you. That is ingratitude for the blessings of Allah. That is the ingratitude of those with blessings.'"
