It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: The prayer in congregation is twenty-five times more virtuous than the prayer of any one of you alone.

It is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: Whoever performs ablution well and completely, then goes to the mosque, but finds that the people have already performed the prayer, Allah will grant him a reward equal to that of those who were present at that prayer, while their reward will not be diminished in the least.

It is narrated from Sayyiduna Uthman bin Affan (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Whoever performs the ‘Isha prayer in congregation, it is as if he has stood in prayer for half the night, and whoever performs the Fajr prayer in congregation, it is as if he has stood in prayer for the entire night.

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) said: If people knew how much (reward and merit) there is in the ‘Isha and Fajr prayers, they would certainly come to perform them, even if they had to crawl on their buttocks.

It is narrated from Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) led the morning prayer and then said: "Is such-and-such a man present?" The people said: "No." Then he (peace and blessings be upon him) said: "Is such-and-such a man present?" The people said: "No." Then he (peace and blessings be upon him) said: "Is such-and-such a man present?" The people said: "No." Then the Messenger of Allah (peace and blessings be upon him) said: "Indeed, these two prayers (Isha and Fajr) are very burdensome upon the hypocrites. If they knew what reward lies in them, they would surely come to perform them, even if they had to crawl on their buttocks. And the first row is like the row of angels, and if you knew its virtue, you would try to outdo one another to attain it. And the prayer performed by a man with two others is purer (i.e., has more reward) than the prayer performed with one man, and the more people there are, the more beloved that prayer is to Allah."

(Second chain) They said: The Messenger of Allah, peace and blessings be upon him, led the Fajr prayer. When he finished the prayer, he asked: Is such-and-such person present? The people remained silent, then some said: No, he is not present. Then the Messenger of Allah, peace and blessings be upon him, said: Indeed, the Fajr and Isha prayers are the heaviest upon the hypocrites, (then he mentioned things similar to the previous narration), and he, peace and blessings be upon him, said: Indeed, the prayer you perform with two men is purer than the prayer you perform with one man, and the prayer you perform with one man is purer than the prayer you perform alone, and the more people there are, the more beloved it is to Allah.

(Third chain of narration) They said: The Messenger of Allah, peace and blessings be upon him, led us in the Fajr prayer. When he finished the prayer, he noticed that there were some people missing among the worshippers. Then he asked: Is such-and-such a man present? We said: Yes. He continued asking about three men in this manner. Then the Messenger of Allah, peace and blessings be upon him, said: Indeed, there is no prayer heavier upon the hypocrites than the ‘Isha and Fajr prayers. (Then the entire above-mentioned hadith was narrated.)

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: If those who stay behind from the Fajr and ‘Isha prayers knew how much reward and merit there is for them in these two, they would surely come to the mosque even if they had to crawl on their buttocks.

Sayyiduna Jabir bin Abdullah (may Allah be pleased with him) narrates: Sayyiduna Ibn Umm Maktum (may Allah be pleased with him) came to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! My house is far from the mosque, and I am also blind, yet I hear the call to prayer (adhan). (So can I pray at home?) The Prophet (peace and blessings be upon him) said: If you hear the adhan, then respond to it, even if you have to come crawling on your buttocks or sliding on your hips.

Sayyiduna Amr bin Umm Maktum رضي الله عنه says: I came to the Messenger of Allah صلى الله عليه وآله وسلم and said: O Messenger of Allah! I am blind and my house is also far from the mosque, and I have a guide but he does not cooperate with me, so will you grant me permission to pray at home? The Prophet صلى الله عليه وآله وسلم asked: Do you hear the call to prayer (adhan)? I said: Yes. The Prophet صلى الله عليه وآله وسلم said: Then I do not find any concession for you.
