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).

Yahya related to me from Malik, from his uncle Abu Suhayl from his father that Umar ibn al-Khattab wrote to Abu Musa saying that he should pray dhuhr when the sun had started to decline, asr when the sun was still pure white before any yellowness had entered it maghrib when the sun had set, and to delay isha as long as he did not sleep, and to pray subh when the stars were all visible and like a haze in the sky and to read in it two long suras from the mufassal.

Abu Sufyan bin Harb informed me that Heraclius had sent a messenger to him while he had been accompanying a caravan from Quraish. They were merchants doing business in Sham (Syria, Palestine, Lebanon and Jordan), at the time when Allah's Apostle had truce with Abu Sufyan and Quraish infidels. So Abu Sufyan and his companions went to Heraclius at Ilya (Jerusalem). Heraclius called them in the court and he had all the senior Roman dignitaries around him. He called for his translator who, translating Heraclius's question said to them, "Who amongst you is closely related to that man who claims to be a Prophet?" Abu Sufyan replied, "I am the nearest relative to him (amongst the group)."

Heraclius said, "Bring him (Abu Sufyan) close to me and make his companions stand behind him." Abu Sufyan added, Heraclius told his translator to tell my companions that he wanted to put some questions to me regarding that man (The Prophet) and that if I told a lie they (my companions) should contradict me." Abu Sufyan added, "By Allah! Had I not been afraid of my companions labeling me a liar, I would not have spoken the truth about the Prophet. The first question he asked me about him was:

'What is his family status amongst you?'

I replied, 'He belongs to a good (noble) family amongst us.'

Heraclius further asked, 'Has anybody amongst you ever claimed the same (i.e. to be a Prophet) before him?'

I replied, 'No.'

He said, 'Was anybody amongst his ancestors a king?'

I replied, 'No.'

Heraclius asked, 'Do the nobles or the poor follow him?'

I replied, 'It is the poor who follow him.'

He said, 'Are his followers increasing decreasing (day by day)?'

I replied, 'They are increasing.'

He then asked, 'Does anybody amongst those who embrace his religion become displeased and renounce the religion afterwards?'

I replied, 'No.'

Heraclius said, 'Have you ever accused him of telling lies before his claim (to be a Prophet)?'

I replied, 'No. '

Heraclius said, 'Does he break his promises?'

I replied, 'No. We are at truce with him but we do not know what he will do in it.' I could not find opportunity to say anything against him except that.

It was said to Salman: Your Prophet teaches you everything, even about excrement. He replied: Yes. He has forbidden us to face the qiblah at the time of easing or urinating, and cleansing with right hand, and cleansing with less than three stones, or cleansing with dung or bone.

Regarding the word ‘sufficient’ in the hadith, Imam al-Nawawi (RA) says: It was said (by scholars) that it means it will suffice him from the night prayer, and others said it means as a protection against the devils, and yet others said it means protection against harmful animals, and it is likely encompassing of all these things (and more).”

Ibn Ḥajar states: “[It] was explicitly reported by ʿĀsim from ʿAlqamah from Ibn Masʿūd, “Whoever recites (the two verses at) the end of Sūrat al-Baqarah, it will be sufficient for him instead of standing in prayer for one night.”

It was related by Muslim (also by al-Bukhari, at-Tirmidhi, and an-Nasa'i).

Yahya related to me from Malik from Amr ibn Yahya ibn Yahya al- Mazini from Ibn Abi Salit that Uthman ibn Affan prayed jumua in Madina and asr in Malal (a place seventeen miles from Madina).

Malik commented, "That was by praying jumua just past midday and then travelling fast."

"Allah's Apostle said, "By Him in Whose Hands my life is, none of you will have faith till he loves me more than his father and his children."

When the Prophet (saws) wanted to relieve himself, he would not raise his garment, until he lowered himself near the ground.

Abu DAwud said: This tradition has been transmitted by 'Abd al-Salam b. Harb on the authority of al-A'mash from Anas b. Malik. This chain of narrators is weak (because A'mash's hearing tradition from Anas b. Malik is not established).

Jabir (Allah be pleased with him) reported Allah's Messenger (may peace be upon him) forbidding the selling (renting of) uncultivated land for two years or three.

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

(The clerk of Al-Mughira) Muawiya wrote to Al-Mughira 'Write to me what you have heard from Allah's Apostle.' So he (Al-Mughira) wrote to him: Allah's Prophet used to say at the end of each prayer: "La ilaha illalla-h wahdahu la sharika lahu, lahul Mulku, wa lahul Hamdu wa hula ala kulli shai'in qadir. 'Allahumma la mani' a lima a'taita, wala mu'tiya lima mana'ta, wala yanfa'u dhuljadd minkal-jadd." He also wrote to him that the Prophet used to forbid (1) Qil and Qal (idle useless talk or that you talk too much about others), (2) Asking too many questions (in disputed Religious matters); (3) And wasting one's wealth by extravagance; (4) and to be undutiful to one's mother (5) and to bury the daughters alive (6) and to prevent your favors (benevolence to others (i.e. not to pay the rights of others (7) And asking others for something (except when it is unavoidable).

I heard Al-Bara' bin `Azib saying, "The Prophet orders us to do seven things and prohibited us from doing seven other things." Then Al-Bara' mentioned the following:-- (1) To pay a visit to the sick (inquiring about his health), (2) to follow funeral processions, (3) to say to a sneezer, "May Allah be merciful to you" (if he says, "Praise be to Allah!"), (4) to return greetings, (5) to help the oppressed, (6) to accept invitations, (7) to help others to fulfill their oaths. (See Hadith No. 753, Vol. 7)

During the life-time of the Prophet we used to take the meat of sacrificed animals (as journey food) to Medina. (See Hadith No. 474 Vol. 7)
