The Prophet (saws) said: The best number of companions is four, the best number in expeditions four hundred, and the best number in armies four thousand; and twelve thousand will not be overcome through smallness of numbers.

Abu Dawud said: What is correct is that this tradition is mursal (i.e. the link of the Companion is missing).

The Prophet said, "Abusing a Muslim is Fusuq (an evil doing) and killing him is Kufr (disbelief)."

Yahya related to me from Malik from Nafi that Abdullah ibn Umar prepared the body of one of Said ibn Zayd's sons for burial and carried it and then entered the mosque and prayed without doing wudu.

Yahya said that Malik was asked whether it was necessary to do wudu because of regurgitating undigested food and he said, "No, wudu is not necessary, but the mouth should be rinsed."

Muhammad ibn Yahya ibn Habban asked Abdullah ibn Abdullah ibn Umar about the reason for Ibn Umar's performing ablution for every prayer, whether he was with or without ablution.

He replied: Asma', daughter of Zayd ibn al-Khattab, reported to me that Abdullah ibn Hanzalah ibn AbuAmir narrated to her that the Messenger of Allah (saws) was earlier commanded to perform ablution for every prayer whether or not he was with ablution.

When it became a burden for him, he was ordered to use tooth-stick for every prayer. As Ibn Umar thought that he had the strength (to perform the ablution for every prayer), he did not give up performing ablution for every prayer.

Abu Dawud said: Ibrahim b. Sa'd narrated this tradition on the authority of Muhammad b. Ishaq, and there he mentions the name of 'Ubaid Allah b. 'Abd Allah (instead of 'Abd Allah b. 'Abd Allah b. 'Umar)

A hadith like this has been narrated on the authority of Humaid with the same chain of transmitters.

Shu'bah said: I heard 'Uthman from the family of Abu 'Aqeel athThaqafi say--but he said. Shu'bah said: And he recited one of these two verses: `whosoever works evil, will have the recompense thereof` [an-Nisa'4:110] or “And those who, when they have committed Fahishah (illegal sexual intercourse)...` [Al 'Imran 3:135).

Another chain reports a similar hadith.

The Prophet used to invoke Allah with the following invocation: 'Rabbi-ghfir-li Khati 'ati wa jahli wa israfi fi `Amri kullihi, wa ma anta a'lamu bihi minni. Allahumma ighfirli khatayaya wa 'amdi, wa jahli wa jiddi, wa kullu dhalika'indi. Allahumma ighrifli ma qaddamtu wa ma akhartu wa ma asrartu wa ma a'lantu. Anta-l-muqaddimu wa anta-l-mu'akh-khiru, wa anta 'ala kulli shai'in qadir.'

The Prophet forbade the selling of foodstuff before receiving it. I consider that all types of sellings should be done similarly.

When the Prophet got up at night to offer the night prayer, he used to say: "Allahumma laka l-hamdu; Anta nuras-samawati wal ardi wa man fihinna. wa laka l-hamdu; Anta qaiyim as-samawati wal ardi wa man flhinna. Wa lakaI-hamdu; Anta-l-,haqqun, wa wa'daka haqqun, wa qauluka haqqun, wa liqauka haqqun, wal-jannatu haqqun, wannaru haqqun, was-sa atu haqqun, wan-nabiyyuna huqqun, Mahammadun haqqun, Allahumma laka aslamtu, wa Alaika tawakkaltu, wa bika amantu, wa ilaika anabtu, wa bika Khasamtu, wa ilaika hakamtu, faghfirli ma qaddamtu wa ma akh-khartu, wa ma asrartu, wa ma a'lantu. Anta al-muqaddimu, wa anta al-mu-'akhkhiru. La ilaha il-la anta (or La ilaha ghairuka)"

The Prophet (saws) said: Judges are of three types, one of whom will go to Paradise and two to Hell. The one who will go to Paradise is a man who knows what is right and gives judgment accordingly; but a man who knows what is right and acts tyrannically in his judgment will go to Hell; and a man who gives judgment for people when he is ignorant will go to Hell.

Abu Dawud said: On this subject this is the soundest tradition, that is, the tradition of Ibn Buraidah: Judges are of three types.

The Prophet used to invoke Allah, saying, "Allahumma ighfirli khati'ati wa jahli wa israfi fi `Amri, wa ma anta a-'lamu bihi minni. Allahumma ighfirli hazali wa jiddi wa khata'i wa amdi, wa kullu dhalika 'indi."

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) forbade (two types of transactions) Mulamasa and Munabadha

Jabir b. 'Abdullah (Allah be pleased with them) reported that Allah's Messenger (may peace be upon him) forbade the types of sales as described before.

'Aishah, the wife of the Prophet (saws) told him that there were four types of marriage during Pre-Islamic period of Ignorance. One type was similar to that of the present day i.e. a man used to ask somebody else for the hand of a girl under his guardianship or for his daughter's hand, and give her Mahr and then marry her. The second type was that a man would say to his wife after she had become clean from her period. "Send for so-and-so and have sexual intercourse with him." Her husband would then keep away from her and would never sleep with her till she got pregnant from the other man with whom she was sleeping. When her pregnancy became evident, he husband would sleep with her if he wished. Her husband did so (i.e. let his wife sleep with some other man) so that he might have a child of noble breed. Such marriage was called as Al-Istibda'. Another type of marriage was that a group of less than ten men would assemble and enter upon a woman, and all of them would have sexual relation with her. If she became pregnant and delivered a child and some days had passed after delivery, she would sent for all of them and none of them would refuse to come, and when they all gathered before her, she would say to them, "You (all) know waht you have done, and now I have given birth to a child. So, it is your child so-and-so!" naming whoever she liked, and her child would follow him and he could not refuse to take him. The fourth type of marriage was that many people would enter upon a lady and she would never refuse anyone who came to her. Those were the prostitutes who used to fix flags at their doors as sign, and he who would wished, could have sexual intercourse with them. If anyone of them got pregnant and delivered a child, then all those men would be gathered for her and they would call the Qa'if (persons skilled in recognizing the likeness of a child to his father) to them and would let the child follow the man (whom they recognized as his father) and she would let him adhere to him and be called his son. The man would not refuse all that. But when Muhammad (saws) was sent with the Truth, he abolished all the types of marriages observed in pre-Islamic period of Ignorance except the type of marriage the people recognize today.

The Prophet was shrouded in three pieces of cloth which were made of Suhul (a type of cotton), and neither a shirt nor a turban were used.

The (foregoing) tradition has also been narrated on the authority of Hatim through the same chain of transmitters with the difference that according to this version both these types of expeditions were seven in number.

‘Umm Athiyah reported the Prophet(saws) as saying “A woman must not observe mourning for more than three (days) except for four months and ten days in the case of a husband and she must not wear a dyed garment except one of the types made of dyed yarn or apply collyrium or touch perfume except for a little costus or azfar when she has been purified after her menstrual courses.

The narrator Ya’qub mentioned the words “except washed clothes” instead of the words “one of the types made of dyed yarn”. Ya’qub also added “She must not apply Henna”

Abu Huraira (Allah be pleased with him) reported that Allah's Messenger (may peace be upon him) forbade a transaction determined by throwing stones, and the type which involves some uncertainty.

The Prophet said, "Five kinds of animals are mischief-doers and can be killed even in the Sanctuary: They are the rat the scorpion, the kite (a type of predatory bird), the crow and the rabid dog."

Mu'awiya bin Qurra reported that `Abdullah bin Al-Maghaffal Al-Muzani said, "I saw Allah's Apostle on the day of the Conquest of Mecca, riding his she-camel and reciting Surat-al-Fath (48) or part of Surat-al-Fath. He recited it in a vibrating and pleasant voice. Then Mu'awiya recited as `Abdullah bin Mughaffal had done and said, "Were I not afraid that the people would crowd around me, I would surely recite in a vibrating pleasant voice as Ibn Mughaffal did, imitating the Prophet." I asked Muawiya, "How did he recite in that tone?" He said thrice, "A, A , A."
