قَالَ النَّبِيُّ (ص): مَا مِنْ صَلاَةٍ يَحْضُرُ وَقْـتُهَا إِلاَّ نَادَى مَلَكٌ بَيْنَ يَدَيِ النَّاسِ أَيُّهَا النَّاسُ قُومُوا إِلـى نِيـرَانِكُمُ الَّتِي أَوْقَدْتُمُوهَا عَلى ظُهُورِكُمْ فَاطْفِئُوهَا بِصَلاَتِكُمْ.
The Messenger of Allah (peace be upon him and his progeny) said: “Whenever the time of each prayer arrives, an Angel announces to the people: (O’ People!) Stand up and extinguish, with prayers, the fire which you have set alight for yourselves.”
"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."
