Muhammad or `Abdullah bin Abu Al-Mujalid said, "Abdullah bin Shaddad and Abu Burda differed
regarding As-Salam, so they sent me to Ibn Abi `Aufa and I asked him about it. He replied, 'In the
lifetime of Allah's Messenger (ﷺ), Abu Bakr and `Umar, we used to pay in advance the prices of wheat,
barley, dried grapes and dates to be delivered later. I also asked Ibn Abza and he, too, replied as
above.' "
Sahih al-Bukhari Book 35, Hadith 6
"A Jew said to his companion: 'Accompany us to this Prophet.' So his companion said: 'Do not say: "Prophet". For if he hears you (say that) then he will be very happy.' So they went to the Messenger of Allah (ﷺ) to question him about nine clear signs. So he said to them: 'Do not associate anything with Allah, nor steal, nor commit unlawful intercourse, nor take a life which Allah has made prohibited prohibited, except for what is required (in the law), nor hasten to damage the reputation of one of power so that he will be killed, nor practice magic, nor consume Riba, nor falsely accuse the chaste woman, nor turn to flee on the day of the march, and for you Jews particularly, to not violate the Sabbath.'" He said: "So they kissed his hands and his feet, and they said: 'We bear witness that you are a Prophet.' So he (ﷺ) said: 'Then what prevents you from following me?' They said: 'Because Dawud supplicated to his Lord that his offspring never be devoid of Prophets and we feared that if we follow you then the Jews will kill us.'"
Jami` at-Tirmidhi Book 42, Hadith 46
I asked 'A'isha about the Messenger of Allah's (ﷺ) voluntary prayers, and she replied: Before the noon prayer, he used to pray four rak'ahs in my house; then would go out and lead the people in prayer; then come in and pray two rak'ahs. He would then lead the people in the sunset prayer; then come in and pray two rak'ahs. Then he would lead the people in the 'Isha' prayer, and enter my house and pray two rak'ahs. He would pray nine rak'ahs during the night, including Witr. At night he would pray for a long time standing and for a long time sitting, and when he recited the Holy Quran while standing, he would bow and prostrate himself from the standing position, and when he recited while sitting, he would bow and prostrate himself from the sitting position, and when it was dawn he would pray two rak'ahs.
Sahih Muslim Book 6, Hadith 129
By Allah, Al-Hasan bin `Ali led large battalions like mountains against Muawiya. `Amr bin Al-As
said (to Muawiya), "I surely see battalions which will not turn back before killing their opponents."
Muawiya who was really the best of the two men said to him, "O `Amr! If these killed those and those
killed these, who would be left with me for the jobs of the public, who would be left with me for their
women, who would be left with me for their children?" Then Muawiya sent two Quraishi men from
the tribe of `Abd-i-Shams called `Abdur Rahman bin Sumura and `Abdullah bin 'Amir bin Kuraiz to
Al-Hasan saying to them, "Go to this man (i.e. Al-Hasan) and negotiate peace with him and talk and
appeal to him." So, they went to Al-Hasan and talked and appealed to him to accept peace. Al-Hasan
said, "We, the offspring of `Abdul Muttalib, have got wealth and people have indulged in killing and
corruption (and money only will appease them)." They said to Al-Hasan, "Muawiya offers you so and
so, and appeals to you and entreats you to accept peace." Al-Hasan said to them, "But who will be
responsible for what you have said?" They said, "We will be responsible for it." So, whatever Al-
Hasan asked they said, "We will be responsible for it for you." So, Al-Hasan concluded a peace treaty
with Muawiya. Al-Hasan (Al-Basri) said: I heard Abu Bakr saying, "I saw Allah's Messenger (ﷺ) on the
pulpit and Al-Hasan bin `Ali was by his side. The Prophet (ﷺ) was looking once at the people and once at
Al-Hasan bin `Ali saying, 'This son of mine is a Saiyid (i.e. a noble) and may Allah make peace
between two big groups of Muslims through him."
