The Messenger of Allah (saws) used to prostrate and sleep (in prostration) and produce puffing sounds (during sleep). Then he would stand and pray and would not perform ablution. I said to him: you prayed but did not perform ablution though you slept (in prostration). He replied: Ablution is necessary for one who sleeps while he is lying down. Uthman and Hannad added: For when he lies down, his joints are relaxed.

Abu Dawud said: The statement "ablution is necessary for one who sleeps while one is lying down" is a munkar (rejected) tradition. It has been narrated only by Yazid Abu Khalid al-Dalani, on the authority of Qatadah. And its earlier part has been narrated by a group (of narrators) from Ibn 'Abbas; they did not mention anything about it. He (Ibn 'Abbas) said: The Prophet (saws) was protected (during his sleep). 'Aishah reported: The Prophet (saws) said: My eyes sleep, but my heart does not sleep. Shu'bah said: Qatadah heard from Abu'l-'Aliyah only four traditions: the tradition about Jonah son of Matthew, the tradition reported by Ibn 'Umar about prayer, the tradition stating that the judges are three, and the tradition narrated by Ibn 'Abbas saying: (This tradition) has been narrated to me by reliable persons ; 'Umar is one of them, and the most reliable of them in my opinion is 'Umar. Abu Dawud said: I asked Ahmad b. Hanbal about the tradition narrated by Yazid al-Dalani. He rebuked me out of respect for him. Then he said: Yazid al-Dalani does not add anything to what has been narrated by the teachers of Qatadah. He did not care of this tradition (due to its weakness).

Malik related to me from Hisham ibn Urwa that his father said that there was only one hadd against a man who slandered a group of people.

Malik said, "If they are on separate occasions there is still only one hadd against him."

Malik related to me from Abu'r-Rijal Muhammad ibn Abd ar-Rahman ibn Haritha ibn an-Numan al- Ansari, then from the Banu'n-Najar from his mother Amra bint Abd ar- Rahman that two men cursed each other in the time of Umar ibn al- Khattab. One of them said to the other, " By Allah, my father is not an adulterer and my mother is not an adulteress." Umar ibn al-Khattab asked advice about that. One person said, "He has praised his father and mother." Another said, "His father and mother have praise other than this. We think that he is to be flogged with the hadd." So Umar flogged him with the hadd of eighty lashes.

Malik said, "There is no hadd in our view except for slander, denial or insinuation, in which one sees that the speaker intends by that denial or slander. Then the hadd is completely imposed on the one who said it."

Malik said, "What is done in our community when a man denies that another man is from his father, is that he deserves the hadd. If the mother who is denied is a slave, then he deserves the hadd as well. '

His father divorced his wife during her menses, so Umar asked the Prophet about that and he said: "Tell him to take her back, then let him divorce her while she is pure or pregnant."
