It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'I was thinking of commanding that the call to prayer be given, then I would tell a man to lead the people in prayer, then I would go out with some other men carrying bundles of wood, and go to people who do not attend the prayer, and burn their houses down around them.'"

It was narrated from Ibn 'Abbas that: The Prophet (ﷺ) said: "Whoever hears the call and does not come, his prayer is not valid, except for those who have an excuse."

Ibn 'Abbas and Ibn 'Umar narrated that: They heard the Prophet (ﷺ) say on his pulpit: "People should desist from failing to attend the congregations, otherwise Allah will seal their hearts, and they will be among the negligent."

It was narrated that Usamah bin Zaid said: "The Messenger of Allah (ﷺ) said: 'Let men desist from failing to attend the congregation, otherwise I will burn their houses down.'"

It was narrated from 'Umar bin Khattab that: The Prophet (ﷺ) used to say: "Whoever performs prayer in congregation at the mosque for forty nights, never missing the first Rak'ah of the 'Isha' prayer, Allah will thereby decree for him salvation from the Fire."

It was narrated that Abu Hurairah said: "The Messenger of Allah (ﷺ) said: 'When one of you enters the mosque, he is in a state of prayer, so long as the prayer keeps him there, and the angels will send prayer upon anyone of you so long as he remains in the place where he prayed, saying: "O Allah, forgive him; O Allah, have mercy on him; O Allah, accept his repentance," so long as he does not commit Hadath nor disturb anyone.'"

It was narrated from Abu Hurairah that: The Prophet (ﷺ) said: "A muslim does not regularly attend the mosques to perform prayer and remember Allah, but Allah feels happy with him just as the family of one who is absent feels happy when he comes back to them."

It was narrated that 'Ali bin Abu Talib said: "The Messenger of Allah (ﷺ) said: 'Whoever builds a mosque for the sake of Allah (from his own wealth), Allah will build a house for him in Paradise.'"

It was narrated that Anas bin Malik said: "The Messenger of Allah (ﷺ) said: 'The Hour will not begin until the people compete in (building) mosques.'"

It was narrated from Wathilah bin Asqa' that: The Prophet (ﷺ) said: "Keep your infants, your insane and your evil ones away from your mosques. Avoid engaging in transactions and disputes, raising your voices, carrying out your prescribed punishments and unsheathing your swords therein. Make places for purification at their gates, and perfume them with incense on Fridays." (Maudu')

It was narrated that Abu Dharr Al-Ghifari said: "I said: 'O Messenger of Allah! Which mosque was built first?' He said: 'Al-Masjid Al-Haram (in Makkah).' I said: 'Then which?' He said: 'then Al-Masjid Al-Aqsa (in Jerusalem).' I said: 'How many years between them?' He said: 'Forty years, but the whole earth is a mosque for you, so pray wherever you are when the time for prayer comes.'"

Mahmud bin Rabi' Al-Ansari, who remembered that the Messenger of Allah (ﷺ) spat a mouthful of water from a bucket into a well that belonged to them, narrated that : 'Itban bin Malik As-Salimi who was the chief of his people Banu Salim and had participated in (the battle of) Badr with the Messenger of Allah (ﷺ) said: "I came to the Messenger of Allah (ﷺ) and said: 'O Messenger of Allah, my sight is failing and the flood comes and prevents me from reaching the mosque of my people, and it is too hard for me to cross the water. Do you think you could come and perform prayer in my house in a place which I can then take as a place of prayer?' He said: 'I will do that.' The following day, the Messenger of Allah (ﷺ) and Abu Bakr came, when the heat of the day had grown intense. He asked permission to enter, and I gave him permission. He did not sit down until he said: 'Where would you like me to perform prayer for you in your house?' I showed him the place where I wanted him to pray, so the Messenger of Allah (ﷺ) stood and we lined up behind him, and he led us in praying two Rak'ah (units). Then I asked him to stay and eat some Khazirah that had been prepared for them.'"

It was narrated that Anas bin Malik said: "One of my paternal uncles made some food for the Prophet (ﷺ) and said to the Prophet: 'I would like you to eat and perform prayer in my house.' So he went to him, and in his house there was one of these Fahl. He ordered that a corner be swept and water sprinkled in it, then he performed prayer and we prayed with him.'" (Sahih)Abu 'Abdullah bin Majah said: A Fahl is a mat that has become black (through use).

It was narrated from 'Aishah that: The Messenger of Allah (ﷺ) commanded that mosque to be built in (Ad-Dur) villages, and that they be purified and perfumed.

It was narrated that Abu Hurairah said: The Messenger of Allah (ﷺ) said: "If you cannot find anywhere (for prayer) except sheep's resting-places and camels' resting-places, then perform prayer in the sheep's resting-places and do not perform prayer in the camels' resting-places."

It was narrated that Fatimah the daughter of the Messenger of Allah (ﷺ) said: "Whenever the Messenger of Allah (ﷺ) entered the mosque he would say: 'Bismillah, was-salamu 'ala Rasulillah, Allahummagh-firli dhunubi waftah li abwaba rahmatika. (In the Name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open to me the gates of Your mercy).' When he left he would say: 'Bismillah, was-salamu 'ala Rasulillah, Allahummagh-firli dhunubi waftah li abwaba fadlika. (In the Name of Allah, and peace be upon the Messenger of Allah. O Allah, forgive me my sins and open to me the gates of Your bounty).'"

It was narrated that Abu Humaid As-Sa'idi said: "The Messenger of Allah (ﷺ) said: 'When anyone of you enters the mosque, let him send peace upon the prophet, then let him say: "Allahummaftah li abwaba rahmatika (O Allah, open to me the gates of Your mercy)." And when he leaves, let him say: "Allahumma inni as'aluka min fadlika. (O Allah, I ask of you from Your bounty)."

It was narrated from Abu Hurairah that: The Mesenger of Allah said: "When anyone of enters the mosque, let him send peace upon the Prophet, then let him say: 'Allahumma aftahli abwaba rahmatik (O Allah, open to me the gates of Your mercy).' And when he leaves, let him send peace upon the Prophet (ﷺ) and say: 'Allahumma- simni minash-shaitanir-rajim (O Allah, protect me from the accursed Shaitan).'"

It was narrated that 'Abdullah said: "Whoever would like to meet Allah tomorrow (i.e. on the Day of Judgment) as a Muslim, let him preserve these five (daily) prayer when the call for them is given, for they are part of the ways of guidance, and Allah prescribed the ways of guidance to your Prophet. By Allah, if each of you prays in his house, you will have abandoned the Sunnah of your Prophet, and if you abandon the Sunnah of your Prophet you will go astray. I remember when no one stayed behind from the prayer except a hypocrite who was known for his hypocrisy. I have a man coming supported by two others, until he joined the row (of worshippers). There is no man who purifies himself and does it well, and comes to the mosque and prays there, but for every step that he takes, Allah raises him in status one degree thereby, and takes away one of his sins."

It was narrated that Abu Sa'eed Al-Khudri said: "The Messenger of Allah (ﷺ) said: 'Whoever leaves his house for the prayer and says: 'Allahumma inni asa'luka bi-haqqis-sa'ilina 'alaika, wa as'aluka bi-haqqi mamshaya hadha, fa inni lam akhruj asharan wa la batran, wa la riya'an, wa la sum'atan, wa kharajtu-ttiqa'a sukhtika wabtigha'a mardatika, fa as'aluka an tu'idhani minan-nari wa an taghfira li dhunubi, Innahu la yaghfirudh-dhunuba illa Anta. (O Allah, I ask You by the right that those who ask of You have over You, and I ask by virtue of this walking of mine, for I am not going out because of pride or vanity, or to show off or make a reputation, rather I am going out because I fear Your wrath and seek Your pleasure. So I ask You to protect me from the Fire and to forgive me my sins, for no one can forgive sins except You),' Allah will turn His Face towards him and seventy thousand angels will pray for his forgiveness."
