Narrated Abdullah ibn Abbas: If anyone hears him who makes the call to prayer and is not prevented from joining the congregation by any excuse--he was asked what an excuse consisted of and replied that it was fear or illness--the prayer he offers will not be accepted from him.

Narrated Amr ibn Zadah, Ibn Umm Maktum: Ibn Umm Maktum asked the Prophet ﷺ saying: Messenger of Allah, I am a blind man, my house is far away (from the mosque), and I have a guide who does not follow me. Is it possible that permission be granted to me for saying prayer in my house? He asked: Do you hear summons (adhan)? He said: Yes. He said: I do not find any permission for you.

Narrated Ibn Umm Maktum: Messenger of Allah, there are many venomous creatures and wild beasts in Madina (so allow me to pray in my house because I am blind). The Prophet ﷺ said: Do you hear the call, "Come to prayer, " "Come to salvation"? (He said: Yes. ) Then you must come. Abu Dawud said: Al-Qasim al-Jarmi has narrated this tradition from Sufyan in a similar manner. But his version does not contain the words "Then you must come. "

Narrated Ubayy ibn Kab: The Messenger of Allah ﷺ led us in the dawn prayer one day. And he said: Is so and so present? They said: No. He (again) asked: Is so and so present? They replied: No. He then said: These two prayers are the ones which are most burdensome to hypocrites. If you knew what they contain (i. e. blessings), you would come to them, even though you had to crawl on your knees. The first row is like that of the angels, and if you knew the nature of its excellence, you would race to join it. A man's prayer said along with another is purer than his prayer said alone, and his prayer with two men is purer than his prayer with one, but if there are more it is more pleasing to Allah, the Almighty, the Majestic.

Uthman bin Affan reported the Messenger of Allah (may peace be him) as saying; if anyone says the night prayer in congregation, he is like one who keeps vigil (in prayer) till midnight; and he who says both the night and dawn prayer in congregation is like one who keeps vigil (in prayer) the whole night.

Narrated Abu Hurairah: The Prophet ﷺ said: The further one is from the mosque, the greater will be one's reward.

Ubayy bin Kaab said: There was a certain person, out of all people of Madina, who used to pray in the mosque. I do not know that any one of them lived at a farther distance than that man. Still he never missed the prayer in congregation in the mosque. I said: it would be better if you buy a donkey and ride it in heat and darkness. He said: I do not like that my house be by the side of the mosque. The discourse reached the Messenger of Allah ﷺ. He said him about it. He said: I did it so that my walking to the mosque and return to my home when I return be recorded. He said: Allah has granted all this to you; Allah has granted all that you reckoned.

Narrated Abu Umamah: The Messenger of Allah ﷺ said: If anyone goes out from his house after performing ablution for saying the prescribed prayer in congregation (in the mosque), his reward will be like that of one who goes for hajj pilgrimage after wearing ihram (robe worn by the hajj pilgrims). And he who goes out to say the mid-morning (duha) prayer, and takes the trouble for this purpose, will take the reward like that of a person who performs Umrah. And a prayer followed by a prayer with no worldly talk during the gap between them will be recorded in Illiyyun.

Abu Hurairah reported the Messenger of Allah ﷺ as saying: Prayer said by a man in congregation is twenty five degrees more excellent than prayer said by him alone in his house or in the market. This is because when any of you performs ablution and does it perfectly, and goes out to the mosque having no intention except praying, and nothing moves him except prayer, then at every step which he takes his rank is elevated by one degree on account of this (walking), and one sin is remitted from him for this (walking), till he enters the mosque. When he enters the mosque, he will be reckoned as praying as long as he will be detained by the prayer. The angels keep on invoking blessing on any of you so long as he remains seated in the place he prayer, saying: O Allah, forgive him; O Allah, have mercy on him; O Allah, accept his repentance so long as he does not harm anyone, or breaks his ablution.

Narrated Abu Saeed al-Khudri: Prayer in congregation is equivalent to twenty-five prayers (offered alone). If he prays in a jungle, and performs its bowing and prostrations perfectly, it becomes equivalent to fifty prayers (in respect of reward). Abu Dawud said: Abd al-Walid bin Ziyad narrated in his version of this tradition: "Prayer said by a single person in a jungle is more excellent by multiplied degrees than prayer said in congregation.
