The Messenger of Allah (peace be upon him) said, "The first matter that the slave will be brought to account for on the Day of Judgment is the prayer. If it is sound, then the rest of his deeds will be sound. And if it is bad, then the rest of his deeds will be bad." [Recorded by al-Tabarani.

The Messenger of Allah (peace be upon him) said, "Allah has obligated five prayers. Whoever excellently performs their ablutions, prays them in their proper times, completes their bows, prostrations and khushu[Khushu in the prayer is where the person’s heart is attuned to the prayer. This feeling in the heart is then reflected on the body. The person remains still and calm. His gaze is also lowered. Even his voice is affected by this feeling in the heart] has a promise from Allah that He will forgive him. And whoever does not do that has no promise from Allah. He may either forgive him or punish him." Recorded by Malik, Ahmad, Abu Dawud, al-Nasa’I and others.

The Messenger of Allah (peace be upon him) said, "If a person had a stream outside his door and he bathed in it five times a day, do you think he would have any filth left on him?" The people said, "No filth would remain on him whatsoever." The Prophet (peace be upon him) then said, "That is like the five daily prayers: Allah wipes away the sins by them." (Recorded by al-Bukhari and Muslim.)
