Riyad as-Salihin

The Companions of the Messenger of Allah (ﷺ) did not consider the abandonment of any action as disbelief except neglecting Salat..

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.".

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.".

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.".

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.".

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.".

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.".

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.".

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.".

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."

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.".

The Messenger of Allah (ﷺ) said, "Arrange the rows in order, stand shoulder to shoulder, close the gaps, be accommodating to your brothers, and do not leave gaps for Satan. Whoever joins up a row, he will be joined to Allah (i.e., to the Mercy of Allah); and whoever cuts off a row, he will be cut off from Allah (i.e., from His Mercy).".

The Messenger of Allah (ﷺ) said, "Stand close together in your rows, keep nearer to one another, and put your necks in line, for by Him in Whose Hands my soul is, I see the Satan entering through the opening in the row like Al- hadhaf (i.e., a type of small black sheep found in Yemen).".

The Messenger of Allah (ﷺ) said, "Fill (complete) the first row, then the one next to it; and if there is any deficiency (incompleteness), it should be in the last row.".

The Messenger of Allah (ﷺ) said, "Allah and His angels invoke blessings upon those who are on the right side of the rows.".

Whenever we performed Salat behind the Messenger of Allah (ﷺ), we liked to be on his right side so that his face might turn towards us (at the end of the Salat). One day, I heard Messenger of Allah (ﷺ) supplicating, "O my Rubb! Shield me from Your Torment on the Day when You will gather (or said, 'resurrect') Your slaves.".

The Messenger of Allah (ﷺ) said, "Let the Imam stand in the middle (so that those praying behind him should be standing both on his right and his left) and close the gaps.".

I heard the Messenger of Allah (ﷺ) saying, "A house will be built in Jannah for every Muslim who offers twelve Rak'ah of optional Salat other than the obligatory Salat in a day and a night (to seek the Pleasure of Allah).".

I performed along with the Messenger of Allah (ﷺ) two Rak'ah of optional prayers before Zuhr and two after the Zuhr (noon prayer), and two after the Friday prayer, and two after the Maghrib (evening) prayer, and two after the 'Isha' (night) prayer.".

The Messenger of Allah (ﷺ) said, "There is a Salat (prayer) between every Adhan and Iqamah; there is a Salat between every Adhan and Iqamah." (While saying the same for the) third time (he (ﷺ) added), "It is for him who desires (to perform it).".
