A blind man had a slave-mother who used to abuse the Prophet (ﷺ) and disparage him. He forbade her but she did not stop. He rebuked her but she did not give up her habit. One night she began to slander the Prophet (ﷺ) and abuse him. So he took a dagger, placed it on her belly, pressed it, and killed her. A child who came between her legs was smeared with the blood that was there. When the morning came, the Prophet (ﷺ) was informed about it.
He assembled the people and said: I adjure by Allah the man who has done this action and I adjure him by my right to him that he should stand up. Jumping over the necks of the people and trembling the man stood up.
He sat before the Prophet (ﷺ) and said: Messenger of Allah! I am her master; she used to abuse you and disparage you. I forbade her, but she did not stop, and I rebuked her, but she did not abandon her habit. I have two sons like pearls from her, and she was my companion. Last night she began to abuse and disparage you. So I took a dagger, put it on her belly and pressed it till I killed her.
Thereupon the Prophet (ﷺ) said: Oh be witness, no retaliation is payable for her blood.
Sunan Abi Dawud Book 40, Hadith 11
We went out with the Prophet (ﷺ) to Khaibar. A man (from the companions) said, "O 'Amir! Let us hear
some of your Huda (camel-driving songs.)" So he sang some of them (i.e. a lyric in harmony with the
camels walk). The Prophet (ﷺ) said, "Who is the driver (of these camels)?" They said, "Amir." The
Prophet said, "May Allah bestow His Mercy on him !" The people said, "O Allah's Messenger (ﷺ)! Would
that you let us enjoy his company longer!" Then 'Amir was killed the following morning. The people
said, "The good deeds of 'Amir are lost as he has killed himself." I returned at the time while they
were talking about that. I went to the Prophet (ﷺ) and said, "O Allah's Prophet! Let my father be sacrificed
for you! The people claim that 'Amir's good deeds are lost." The Prophet (ﷺ) said, "Whoever says so is a
liar, for 'Amir will have a double reward as he exerted himself to obey Allah and fought in Allah's
Cause. No other way of killing would have granted him greater reward."
Sahih al-Bukhari Book 87, Hadith 29
I went out with `Abdullah , to Mecca and when we proceeded to am' he offered the two prayers (the
Maghrib and the `Isha') together, making the Adhan and Iqama separately for each prayer. He took his
supper in between the two prayers. He offered the Fajr prayer as soon as the day dawned. Some
people said, "The day had dawned (at the time of the prayer)," and others said, "The day had not
dawned." `Abdullah then said, "Allah's Messenger (ﷺ) said, 'These two prayers have been shifted from their
stated times at this place only (at Al-Muzdalifa); first: The Maghrib and the `Isha'. So the people
should not arrive at Al-Muzdalifa till the time of the `Isha' prayer has become due. The second prayer
is the morning prayer which is offered at this hour.' " Then `Abdullah stayed there till it became a bit
brighter. He then said, "If the chief of the believers hastened onwards to Mina just now, then he had
indeed followed the Sunna." I do not know which proceeded the other, his (`Abdullah's) statement or
the departure of `Uthman . `Abdullah was reciting Talbiya till he threw pebbles at the Jamrat-Al-
`Aqaba on the Day of Nahr (slaughtering) (that is the 10th of Dhul-Hijja).
Sahih al-Bukhari Book 25, Hadith 163
"I heard the Messenger of Allah say: 'Allahumma inni a'udhu bika minal-kasali, walharami, wal-maghrami, wal-ma'thami, wa a'udhu bika min sharril-masihid-dajjali, wa a'udhu bika min 'adhabil-qabri, wa a'udhu bika min 'adhabin-nar (O Allah, I seek refuge in You from laziness, old age, debt and sin, and I seek refuge in You from the evil of the Al-Masihid-Dajjal, and I seek refuge in You from the torment of the grave, and I seek refuge in You from the punishment of the Fire.)'"
