I found a purse containing one hundred Diners. So I went to the Prophet (and informed him about it),
he said, "Make public announcement about it for one year" I did so, but nobody turned up to claim it,
so I again went to the Prophet (ﷺ) who said, "Make public announcement for another year." I did, but
none turned up to claim it. I went to him for the third time and he said, "Keep the container and the
string which is used for its tying and count the money it contains and if its owner comes, give it to
him; otherwise, utilize it."
The sub-narrator Salama said, "I met him (Suwaid, another sub-narrator) in Mecca and he said, 'I don't
know whether Ubai made the announcement for three years or just one year.' "
Sahih al-Bukhari Book 45, Hadith 1
"The sun was eclipsed during the lifetime of the Messenger of Allah (ﷺ). He stood and said the takbir, and the people formed rows behind him. The Messenger of Allah (ﷺ) recited for a long time, then he said the takbir and bowed for a long time, then he raised his head and said: Sami Allahu liman hamidah, Rabbana wa lakal-hamd. Then he stood and recited for a long time, but it was a shorter recitation than the first recitation, then he said the takbir and bowed but it was shorter than the first bowing. Then he said: Sami Allahu liman hamidah, then he prostrated. In this manner, he bowed four times, and the eclipse ended before he had finished. Then he stood and addressed the people. He praised and glorified Allah (SWT), the Mighty and Sublime, as He deserves, then he said: The sun and moon are two of the signs of Allah (SWT), Most High. They do not become eclipsed for the death or birth of anyone. If you see that (eclipsed) then pray until it ends. And the Messenger of Allah (ﷺ) said: While I was standing just now I saw everything you have been promised. When you saw me moving forward, I wanted to take a cluster of fruit from Paradise. And I saw Hell; parts of it were consuming other parts when you saw me step backward. And I saw therein Ibn Luhayy, who was the first one to establish the Sa'ibah.'"
Sunan an-Nasa'i Book 16, Hadith 14
Abd Yazid, the father of Rukanah and his brothers, divorced Umm Rukanah and married a woman of the tribe of Muzaynah. She went to the Prophet (ﷺ) and said: He is of no use to me except that he is as useful to me as a hair; and she took a hair from her head. So separate me from him. The Prophet (ﷺ) became furious. He called on Rukanah and his brothers. He then said to those who were sitting beside him. Do you see so-and-so who resembles Abdu Yazid in respect of so-and-so; and so-and-so who resembles him in respect of so-and-so? They replied: Yes. The Prophet (ﷺ) said to Abdu Yazid: Divorce her. Then he did so. He said: Take your wife, the mother of Rukanah and his brothers, back in marriage. He said: I have divorced her by three pronouncements, Messenger of Allah. He said: I know: take her back. He then recited the verse: "O Prophet, when you divorce women, divorce them at their appointed periods."
Abu Dawud said: The tradition narrated by Nafi' b. 'Ujair and 'Abd Allah b. Yazid b. Rukanah from his father on the authority of his grandfather reads: Rukanah divorced his wife absolutely (i.e. irrevocable divorce). The Prophet (ﷺ) restored her to him. This version is sounder (than other versions), for they (i.e. these narrators) are the children of his man, and the members of the family are more aware of his case. Rukanah divorced his wife absolutely (i.e. three divorces in one pronouncement) and the Prophet (ﷺ) made it a single divorce.
