"The Messenger of Allah said: 'The Hour will not begin until the people compete in (building) mosques.'"

"The Messenger of Allah said: 'All the earth is a mosque, except for graveyards and Hammam.'"

A man among the Ansar sent word to the Messenger of Allah saying: "Come and designate a place in my house where I can perform prayer,' that was after he had become blind. So he went and did that.

"The Messenger of Allah said: 'Whoever removes something harmful from the mosque, Allah will build for him a house in Paradise.'"

The Prophet saw some sputum in the prayer direction of the mosque and he became so angry that his face turned red. Then a woman from among the Ansar came and scraped it off, and put some Khaluq on that spot. The Messenger of Allah said: "How good this is."

The Prophet scratched some spittle from the prayer direction of the mosque.

"The Prophet said: 'Perform prayer in the sheep's resting-places and do not perform prayer in the camels' resting-places, for they were created from the devils."

"The Messenger of Allah said: 'When one of you performs ablution and does it well, then he comes to the mosque with no other motive but prayer and not seeking anything other than the prayer, he does not take one step but Allah raises him in status one degree thereby, and takes away one of his sins, until he enters the mosque. When he enters the mosque he is in a state of prayer so long as he is waiting for the prayer.'"

"The Messenger of Allah said: 'Those who walk to the mosque in the dark are those who are diving into the mercy of Allah.'"

"I heard the Messenger of Allah say: 'Whoever builds a mosque in which the Name of Allah is mentioned, Allah will build a house for him in Paradise.'"

The Prophet 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')

"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.'"

The Messenger of Allah commanded that places of prayer be established in villages, and that they be purified and perfumed.

The Messenger of Allah saw some sputum on the wall of the mosque. He picked up a stone and scraped it off, then he said, "If anyone of you needs to spit, he should not spit in fro not of him or to his right; let him spit to his right; let him spit to his left or under his left foot."

"The Messenger of Allah saw some sputum in the prayer direction of the mosque, when he was praying in front of the people. He scratched it off, then when the prayer was over, he said: 'When anyone of you is performing prayer, Allah is before him, so none of you should spit toward the front while praying.'"

"The Messenger of Allah performed prayer, then a man said: 'Who was looking for the red camel?' The Prophet said: 'May you not find it! The mosques were built for that for which they were built.'"

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 and say: 'Allahumma- simni minash-shaitanir-rajim (O Allah, protect me from the accursed Shaitan).'"

The Messenger of Allah said: "When the Iqamah is called for the prayer, do not come running. Come walking with tranquility. Whatever you catch up with, pray, and whatever you miss, complete it."

He heard the Messenger of Allah say: 'Shall I not tell you of something by means of which Allah expiates for sins and increases good deeds?' They said: 'Yes, O Messenger of Allah.' He said: 'Performing ablution properly despite difficulties, increasing the number of steps one takes towards the mosque and waiting for the next prayer after prayer.'
