Allah's Messenger (ﷺ) said, "On the Day of Resurrection the Kanz (Treasure or wealth of which, Zakat has
not been paid) of anyone of you will appear in the shape of a huge bald headed poisonous male snake
and its owner will run away from it, but it will follow him and say, 'I am your Kanz.'" The Prophet (ﷺ)
added, "By Allah, that snake will keep on following him until he stretches out his hand and let the
snake swallow it." Allah's Messenger (ﷺ) added, "If the owner of camels does not pay their Zakat, then, on
the Day of Resurrection those camels will come to him and will strike his face with their hooves."
Some people said: Concerning a man who has camels, and is afraid that Zakat will be due so he sells
those camels for similar camels or for sheep or cows or money one day before Zakat becomes due in
order to avoid payment of their Zakat cunningly! "He has not to pay anything." The same scholar said,
"If one pays Zakat of his camels one day or one year prior to the end of the year (by the end of which
Zakat becomes due), his Zakat will be valid."
Sahih al-Bukhari Book 90, Hadith 5
(daughter of Abu Sufyan) I said, "O Allah's Messenger (ﷺ)! Marry my sister. the daughter of Abu Sufyan."
The Prophet (ﷺ) said, "Do you like that?" I replied, "Yes, for even now I am not your only wife and I like
that my sister should share the good with me." The Prophet (ﷺ) said, "But that is not lawful for me." I
said, We have heard that you want to marry the daughter of Abu Salama." He said, "(You mean) the
daughter of Um Salama?" I said, "Yes." He said, "Even if she were not my step-daughter, she would
be unlawful for me to marry as she is my foster niece. I and Abu Salama were suckled by Thuwaiba.
So you should not present to me your daughters or your sisters (in marriage)."
Narrated 'Urwa:
Thuwaiba was the freed slave girl of Abu Lahb whom he had manumitted, and then she suckled the
Prophet. When Abu Lahb died, one of his relatives saw him in a dream in a very bad state and asked
him, "What have you encountered?" Abu Lahb said, "I have not found any rest since I left you, except
that I have been given water to drink in this (the space between his thumb and other fingers) and that
is because of my manumitting Thuwaiba."
Sahih al-Bukhari Book 67, Hadith 39
Yahya related to me from Malik from Ata ibn Abdullah al-Khurasani that Said ibn al-Musayyab said, "A bedouin came to the Messenger of Allah, may Allah bless him and grant him peace, beating his breast and tearing out his hair and saying, 'I am destroyed.' The Messenger of Allah, may Allah bless him and grant him peace, said, 'Why is that?', and he said, 'I had intercourse with my wife while fasting in Ramadan.' The Messenger of Allah, may Allah bless him and grant him peace, asked him, 'Are you able to free a slave?', and the man said, 'No.' Then he asked him, 'Are you able to give away a camel?', and the man replied, 'No.' He said, 'Sit own,' and someone brought a large basket of dates to the Messenger of Allah, may Allah bless him and grant him peace, and he said to the man, 'Take this and give it away as sadaqa.' The man said, 'There is no one more needy than me,' and (the Messenger of Allah, may Allah bless him and grant him peace), said, 'Eat them, and fast one day for the day when you had intercourse.' " Malik said that Ata said that he had asked Said ibn al-Musayyab how many dates there were in that basket, and he said, "Between fifteen and twenty sas.''
Muwatta Malik Book 18, Hadith 31
I used to teach Quran to 'Abdur-Rahman bin Auf. When Umar performed his last Hajj, 'Abdur-Rahman said (to me) at Mina, "Would that you had seen Chief of the believers today! A man came to him and said, "So-and-so has said, "If Chief of the Believers died, we will give the oath of allegiance to such-and-such person,' 'Umar said, 'I will get up tonight and warn those who want to usurp the people's rights.' I said, 'Do not do so, for the season (of Hajj) gathers the riffraff mob who will form the majority of your audience, and I am afraid that they will not understand (the meaning of) your saying properly and may spread (an incorrect statement) everywhere. You should wait till we reach Medina, the place of migration and the place of the Sunna (the Prophet's Traditions). There you will meet the companions of Allah's Messenger (ﷺ) from the Muhajirin and the Ansar who will understand your statement and place it in its proper position' 'Umar said, 'By Allah, I shall do so the first time I stand (to address the people) in Medina.' When we reached Medina, 'Umar (in a Friday Khutba-sermon) said, "No doubt, Allah sent Muhammad with the Truth and revealed to him the Book (Quran), and among what was revealed, was the Verse of Ar-Rajm (stoning adulterers to death).'" (See Hadith No. 817,Vol. 8)
