‘Abdallah b. ‘Amr b. al-‘As told of God’s messenger saying to him, “Have I not been informed, ‘Abdallah, that you fast during the day and get up at night for prayer?” [Mirqat explains this as meaning all night.] When he replied that that was so, he said, “Do not do it. Fast and break your fast, get up for prayer and sleep, for you have a duty to your body, your eye, your wife, and your visitors. May he who observe a perpetual fast never fast!* Fasting three days every month is equivalent to a perpetual fast. Fast three days every month and recite the Qur'an every month.” When he replied that he was able to do more than that, he said, “Observe the most excellent fast, that of David, fasting every second day, and recite the Qur’an once every seven nights, but do no more than that.” * Cf. the similar phrase in the tradition of Abu Qatada (p.434). Some hold that the meaning here is, ‘He who observes a perpetual fast has not fasted.’ (Bukhari and Muslim.)

“The Messenger of Allah (saw) delivered a sermon to us and said: ‘O people! Repent to Allah before you die. Hasten to do good deeds before you become preoccupied (because of sickness and old age). Uphold the relationship that exists between you and your Lord by remembering Him a great deal and by giving a great deal of charity in secret and openly. (Then) you will be granted provision and Divine support, and your condition will improve. Know that Allah has enjoined Friday upon you in this place of mine, on this day, in this month, in this year, until the Day of Resurrection. Whoever abandons it, whether during my lifetime or after I am gone, whether he has a just or an unjust ruler, whether he takes it lightly or denies (that it is obligatory), may Allah cause him to lose all sense of tranquility and contentment, and may He not bless him in his affairs. Indeed, his prayer will not be valid, his Zakat will not be valid, his Hajj will not be valid, his fasting will not be valid, and his righteous deeds will not be accepted, until he repents. Whoever repents, Allah will accept his repentance. No woman should be appointed as Imam over a man, no Bedouin should be appointed as Imam over a Muhajir, no immoral person should be appointed as Imam over a (true) believer, unless that is forced upon him and he fears his sword or whip.’”

"One prayer in the Masjid of the Messenger of Allah (PBUH) is better than one thousand prayers offered in other mosques, except Al-Masjid Al-Haram, for the Messenger of Allah (PBUH) was the last of the prophets and his Masjid was the last of the Masjids." Abu Salamah and Abu 'Abdullah said: "We do not doubt that Abu Hurairah was speaking on the basis of the Hadith of the Messenger of Allah (PBUH), but we could not verify that Hadith with Abu Hurairah before he died. Then we remembered that and we blamed one another for not having spoken to Abu Hurairah about that, so that he could attribute it to the Messenger of Allah (PBUH) if he had indeed heard it from him. While we were arguing, we went and sat down with 'Abdullah bin Ibrahim bin Qariz, and we told him about the Hadith and how we had been negligent in not checking it with Abu Hurairah. 'Abdullah bin Ibrahim said to us: 'I bear witness that I heard Abu Hurairah say: The Messenger of Allah (PBUH) said: I am the last of the prophets and it is the last of the Masjids.'"

Allah’s Messenger (saw) said, “Whoever performs ablution on Friday has done a good thing and he who takes bath, taking bath is better (for him).” [Reported by Al-Khamsa and At-Tirmidhi graded it Hasan (fair).]

Allah's Messenger (SAW) said, "The prayer offered in congregation is twenty-seven degrees more rewardable than a prayer offered by a single person." [Agreed upon].

“I asked the Messenger of Allah (saw): ‘Which is better prayer in my house or prayer in the mosque?’ He said: ‘Do you not see how close my house is to the mosque?’ But praying in my house is dearer to me than praying in the mosque, apart from the prescribed prayers.’”

“A man came to the Messenger of Allah (saw) at the first pillar and said: ‘O Messenger of Allah, which Jihad is best?’ but he kept quiet. When he saw the second Pillar, he asked again, and he kept quiet. When he stoned ‘Aqabah Pillar, he placed his foot in the stirrup, to ride, and said: ‘Where is the one who was asking?’ (The man) said: ‘Here I am, O Messenger of Allah.’ He said: ‘A word of truth spoken to an unjust ruler.’”

“I was with the Messenger of Allah (saw) and a man from among the Ansar came to him and greeted the Prophet (saw) with Salam. Then he said: ‘O Messenger of Allah, which of the believers is best?’ He said: ‘He who has the best manners among them.’ He said: ‘Which of them is wisest?’ He said: ‘The one who remembers death the most and is best in preparing for it. Those are the wisest.’”
