The chief purpose of Salah in Islam is to act as a person's communication with and remembrance of God. By reciting "The Opening", the first chapter of the Qur'an, as required in all daily worship, the worshipper can stand before God, thank and praise Him, and to ask for guidance along the Straight Path.
 
In addition, daily worship remind Muslims to give thanks for God's blessings and that submission to God takes precedence over all other concerns, thereby revolving their life around God and submitting to His will. Worship also serves as a formal method of remembering Allah, or dhikr .
 
In the Qur'an, it is written that:

"The true believers are those who feel fear in their hearts when God is mentioned. And when His Revelations are recited to them, they find their faith strengthened. They do their best and then put their trust in their Lord." [Quran 8:2]

 
"To those whose hearts, when God is mentioned, are filled with fear, who show patient perseverance over their afflictions, keep up regular prayer, and spend (in charity) out of what we have bestowed upon them." [Quran 22:35]

 
Salah is also cited as a means of restraining a believer from social wrongs and moral deviancy. [Quran 29:45] According to a hadith in the collection Sahih Bukhari, Muhammad considered salah "the best deed”
 
The Ahadith provide further details; as for example, when the Qur'an refers to three daily prayers (suras 11:114; 17:78–79; 30:17–18 and possibly 24:58), while the five daily prayers stipulated by the later Ahadith have been adopted by Muslims.[5][not in citation given]
 
Abu Huraira RadiyAllahu `anhu narrates that once Muhammad asked his companions,

'Do you think that dirt can remain on a person bathing five times a day in a brook running in front of his door?' 'No', replied the compan­ions, 'No dirt can remain on his body.' Muhammad remarked: 'So, exactly similar is the effect of salat offered five times a day. With the grace of Allah, it washes away all the sins'.(Bukhari, Muslim)

 
Abu Umamah narrates that the Muhammad said,

"Allah does not Listen to anything from His servant as He does to the two rakahs (of prayer) that he offers. Mercy descends over the servant's head as long as he remains in prayer." (Tirmidhi and Ahmad) As-Suyuti considers it sahih."

 
In Al-Muwatta, Imam Malik ibn Anas says: "It reached me that the Prophet said:

'(Try to) keep to the straight path although you won't be able to do so completely; and know that the best of your deeds is salah, and only a (true) believer preserves his wudhu.'"

 
Abu Zar RadiyAllahu `anhu narrates that once Muhammad came out of his house. It was autumn and the leaves were falling off the trees. He caught a branch of a tree and its leaves began to drop in large number. At this he remarked, 'O, Abu Zar! when a Muslim offers his salat to please Allah, his sins are shed away from him just as these leaves are falling off this tree.'(Ahmad)
 
Sabrah bin Ma'bad Al-Juhani reported: Muhammad said,

"Teach a boy Salat when he attains the age of seven years, and punish him (if he does not offer it) at ten." (Abu Dawood)

 
Abu Huraira narrated: Muhammad said,

"The angels keep on asking Allah's forgiveness for anyone of you, as long as he is at his Mu,salla (praying place) and he does not pass wind (Hadath). They say, 'O Allah! Forgive him, O Allah! be Merciful to him." (Sahih Al-Bukhari, Volume 1, Book 8, Hadith #436)

Uthman bin Affan narrates that Muhammad said,

"He who performed wudhu for salat and performed it properly and then went on foot to offer the obligatory salat and offered it along with the people or in congregation or in the masjid, Allah would forgive his sins." from Muslim

 
Abu Darda narrates that Muhammad said,

"If three persons in a village or a forest do not offer the congregational salat, then shaitan fully overpowers them. So make it obligatory on yourself to offer salat in congregation. For undoubtedly the wolf eats only the stray goat." from Abu Dawood.
