Narrated Abu Jamra: I was an interpreter between the people and Ibn `Abbas. Once Ibn `Abbas said that a delegation of the tribe of `Abdul Qais came to the Prophet who asked them, "Who are the people (i.e. you)? (Or) who are the delegates?" They replied, "We are from the tribe of Rabi`a." Then the Prophet said to them, "Welcome, O people (or said, "O delegation (of `Abdul Qais).") Neither will you have disgrace nor will you regret." They said, "We have come to you from a distant place and there is the tribe of the infidels of Mudar intervening between you and us and we cannot come to you except in the sacred month. So please order us to do something good (religious deeds) and that we may also inform our people whom we have left behind (at home) and that we may enter Paradise (by acting on them.)" The Prophet ordered them to do four things, and forbade them from four things. He ordered them to believe in Allah Alone, the Honorable the Majestic and said to them, "Do you know what is meant by believing in Allah Alone?" They replied, "Allah and His Apostle know better." Thereupon the Prophet said, "(That means to testify that none has the right to be worshipped but Allah and that Muhammad is His Apostle, to offer prayers perfectly, to pay Zakat, to observe fasts during the month of Ramadan, (and) to pay Al-Khumus (one fifth of the booty to be given in Allah's cause)." Then he forbade them four things, namely Ad-Dubba.' Hantam, Muzaffat (and) An-Naqir or Muqaiyar (These were the names of pots in which alcoholic drinks used to be prepared). The Prophet further said, "Memorize them (these instructions) and tell them to the people whom you have left behind."

Narrated `Abdullah bin Abi Mulaika: `Uqba bin Al-Harith said that he had married the daughter of Abi Ihab bin `Aziz. Later on a woman came to him and said, "I have suckled (nursed) `Uqba and the woman whom he married (his wife) at my breast." `Uqba said to her, "Neither I knew that you have suckled (nursed) me nor did you tell me." Then he rode over to see Allah's Apostle at Medina, and asked him about it. Allah's Apostle said, "How can you keep her as a wife when it has been said (that she is your foster-sister)?" Then `Uqba divorced her, and she married another man.

Narrated `Umar: My Ansari neighbor from Bani Umaiya bin Zaid who used to live at `Awali Al-Medina and used to visit the Prophet by turns. He used to go one day and I another day. When I went I used to bring the news of that day regarding the Divine Inspiration and other things, and when he went, he used to do the same for me. Once my Ansari friend, in his turn (on returning from the Prophet), knocked violently at my door and asked if I was there." I became horrified and came out to him. He said, "Today a great thing has happened." I then went to Hafsa and saw her weeping. I asked her, "Did Allah's Apostle divorce you all?" She replied, "I do not know." Then, I entered upon the Prophet and said while standing, "Have you divorced your wives?" The Prophet replied in the negative. On what I said, "Allahu-Akbar (Allah is Greater)." (See Hadith No. 119, Vol. 3 for details)

Narrated Abu Mas`ud Al-Ansari: Once a man said to Allah's Apostle "O Allah's Apostle! I may not attend the (compulsory congregational) prayer because so and so (the Imam) prolongs the prayer when he leads us for it. The narrator added: "I never saw the Prophet more furious in giving advice than he was on that day. The Prophet said, "O people! Some of you make others dislike good deeds (the prayers). So whoever leads the people in prayer should shorten it because among them there are the sick the weak and the needy (having some jobs to do).

Narrated Zaid bin Khalid Al-Juhani: A man asked the Prophet about the picking up of a "Luqata" (fallen lost thing). The Prophet replied, "Recognize and remember its tying material and its container, and make public announcement (about it) for one year, then utilize it but give it to its owner if he comes." Then the person asked about the lost camel. On that, the Prophet got angry and his cheeks or his Face became red and he said, "You have no concern with it as it has its water container, and its feet and it will reach water, and eat (the leaves) of trees till its owner finds it." The man then asked about the lost sheep. The Prophet replied, "It is either for you, for your brother (another person) or for the wolf."

Narrated Abu Musa: The Prophet was asked about things which he did not like, but when the questioners insisted, the Prophet got angry. He then said to the people, "Ask me anything you like." A man asked, "Who is my father?" The Prophet replied, "Your father is Hudhafa." Then another man got up and said, "Who is my father, O Allah's Apostle ?" He replied, "Your father is Salim, Maula (the freed slave) of Shaiba." So when `Umar saw that (the anger) on the face of the Prophet he said, "O Allah's Apostle! We repent to Allah (Our offending you).

Narrated Anas bin Malik: One day Allah's Apostle came out (before the people) and `Abdullah bin Hudhafa stood up and asked (him) "Who is my father?" The Prophet replied, "Your father is Hudhafa." The Prophet told them repeatedly (in anger) to ask him anything they liked. `Umar knelt down before the Prophet and said thrice, "We accept Allah as (our) Lord and Islam as (our) religion and Muhammad as (our) Prophet." After that the Prophet became silent.

Thus, the Messenger of Allah ( صلی اللہ علیہ وسلم ) said «ألا وقول الزور» and kept repeating it three times, and Ibn Umar (may Allah be pleased with them both) said that the Prophet ( صلی اللہ علیہ وسلم ) said: "I have conveyed (the message to you)." (This phrase) he ( صلی اللہ علیہ وسلم ) repeated three times.

Narrated Anas: Whenever the Prophet asked permission to enter, he knocked the door thrice with greeting and whenever he spoke a sentence (said a thing) he used to repeat it thrice. (See Hadith No. 261, Vol. 8).

Narrated Anas: Whenever the Prophet spoke a sentence (said a thing), he used to repeat it thrice so that the people could understand it properly from him and whenever he asked permission to enter, (he knocked the door) thrice with greeting.
