'Uthman bin 'Affan (May Allah be pleased with him) reported: I heard the Messenger of Allah (ﷺ) saying: "One who performs 'Isha' prayer in congregation, is as if he has performed Salat for half of the night. And one who performs the Fajr prayer in congregation, is as if he has performed Salat the whole night." The narration of At-Tirmidhi says: 'Uthman bin Affan (May Allah be pleased with him) narrated that he had heard the Messenger of Allah (ﷺ) saying: "He who attends 'Isha' in congregation, is as if he has performed Salat for half of the night; and he who attends 'Isha' and Fajr prayers in congregation, is as if he has performed Salat for the whole night."

Abu Hurairah (May Allah be pleased with him)reported: The Messenger of Allah (ﷺ) said, "If they knew the merits of Salat after nightfall ('Isha') and the morning (Fajr) Salat, they would come to them even if they had to crawl to do so." This is part of a long Hadith which has already been mentioned. See Hadith No. 1033.

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "No Salat is more burdensome to the hypocrites than the Fajr (dawn) prayer and the 'Isha' (night) prayer; and if they knew their merits, they would come to them even if they had to crawl to do so." .

Ibn Mas'ud (May Allah be pleased with him) reported: I asked the Messenger of Allah (ﷺ): "Which act is the best?" He (ﷺ) said, "As-Salat at their fixed times." I asked, "What next?" He (ﷺ) said, "Being dutiful to parents." I asked, "What next?" He (ﷺ) said, "Striving (Jihad) in the way of Allah." .

Ibn 'Umar (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "Islam is based on five (pillars): testifying that there is no true god except Allah and that Muhammad (ﷺ) is His slave and Messenger; performing of Salat (Iqamat-as-Salat); the payment of Zakat; performing Hajj (pilgrimage) to the House ; and Saum (fasting) during the month of Ramadan." .

Ibn 'Umar (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) said, "I have been commanded to fight against the people till they testify La ilaha illAllah (There is no true god except Allah) and that Muhammad (ﷺ) is His slave and Messenger, and to establish As-Salat (Iqamat-as-Salat), and to pay Zakat; and if they do this, then their blood and property are secured except by the rights of Islam, and their accountability is left to Allah." .

Mu'adh (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) sent me as a governor to Yemen and (at the time of departure) he instructed me thus: "You will go to people of the Scripture (i.e., the Jews and the Christians). First of all invite them to testify that La ilaha ill Allah (There is no true god except Allah) and that Muhammad (ﷺ) is His slave and Messenger; and if they accept this, then tell them that Allah has enjoined upon them five Salat (prayers) during the day and night; and if they accept it, then tell them that Allah has made the payment of Zakat obligatory upon them. It should be collected from their rich and distributed among their poor; and if they agree to it, don't take (as a share of Zakat) the best of their properties. Beware of the supplications of the oppressed, for there is no barrier between it and Allah." .

Jabir (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "Between a man and disbelief and paganism is the abandonment of Salat (prayer)." .

Buraidah (May Allah be pleased with him) reported: Messenger of Allah (ﷺ) said, "That which differentiates us from the disbelievers and hypocrites is our performance of Salat. He who abandons it, becomes a disbeliever." .

Shaqiq bin 'Abdullah reported: The Companions of the Messenger of Allah (ﷺ) did not consider the abandonment of any action as disbelief except neglecting Salat. .

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "The first of man's deeds for which he will be called to account on the Day of Resurrection will be Salat. If it is found to be perfect, he will be safe and successful; but if it is incomplete, he will be unfortunate and a loser. If any shortcoming is found in the obligatory Salat, the Glorious and Exalted Rubb will command to see whether His slave has offered any voluntary Salat so that the obligatory Salat may be made up by it. Then the rest of his actions will be treated in the same manner." .

Jabir bin Samurah (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) came out to us (once) and said, "Why do you not stand in rows as the angels do before their Rubb?" We asked: "O Messenger of Allah! how do the angels stand in rows before their Rubb?" He (ﷺ) replied, "They complete each row beginning with the first and filling all the gaps." .

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "If people came to know the blessing of calling Adhan and the standing in the first row, they could do nothing but would draw lots to secure these privileges." .

Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "The best of the men's rows (in Salat) is the first row and the worst is the last; but the best of the woman's row is the last and the worst of their rows is the first." .

Abu Sa'id Al-Khudri (May Allah be pleased with him) reported: When the Messenger of Allah (ﷺ) perceived a tendency among his Companions to stand in the back rows, he said to them, "Come forward and be close to me and let those who come after you, follow your lead. If people continue to fall behind (i.e., in acquiring virtues), Allah puts them behind." .

Abu Mas'ud (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) used to gently pat our shoulders when we were standing in rows at the time of Salat and say, "Keep (the rows) straight; do not differ from each other lest your hearts should suffer from discord. Let those of you who are mature and prudent be nearer to me, and then those who are next to them." .

Anas (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "Keep your rows straight (during Salat in congregation), for keeping the rows straight is part of the perfection of Salat." .

Anas (May Allah be pleased with him) reported: When the Iqamah had been announced, the Messenger of Allah (ﷺ) turned his face towards us and said: "Make your rows straight and stand close together, for I can see you from behind my back." .

An-Nu'man bin Bashir (May Allah be pleased with them) reported: I heard the Messenger of Allah (ﷺ) saying, "Straighten your rows; otherwise, Allah will create dissension among you." . The narration in Muslim is: An-Nu'man bin Bashir (May Allah be pleased with them) said: The Messenger of Allah (ﷺ) directed us to keep our rows as straight as arrows. He continued stressing this until he realized that we had learnt it from him (recognized its significance). One day he came into the mosque and stood up. He was just about to say Takbir (Allah is Greater) when he noticed a man whose chest was projected from the row, so he said, "O slaves of Allah, you must straighten your rows or Allah will certainly put your faces in opposite directions."

Al-Bara' bin 'Azib (May Allah be pleased with them) reported: The Messenger of Allah (ﷺ) used to pass between the rows from one end to the other, touching our chest and shoulders (i.e., arranging the rows) in line and saying, "Do not be out of line; otherwise your hearts will be in disagreement". He would add, "Allah and His angels invoke blessings upon the first rows." .
