Salatul Layl

Benefits of Salatul Layl are much more than what we can understand or imagine. According to authentic Hadeeths from the Prophet Muhammad (SAWA), the gate for getting every benefit and bounty and blessings and success in the life and hereafter is performing Salatul Layl.

'These are some Hadeeths in this important worship: 
"The prayer of the night is to prove light in the heart of the slave: ""If the slave abandons his master in the dark and dark center of the night, Allah has proved light in his heart."""
"Second: The prayer of the night is inherited the honor of the honor of the believer. ""The honor of the believer is his connections at night."""
Third: Night prayer requires the consent of Allah and the highest thing that the believer can bring to God.
Fourth: Night prayer inherits the health of the hull:
"Good face , "" Whoever has been so many of his connections at night , and his face has been improved by day , and said : "" Can't you see that the prayers at night are the best people in the face?""" Because they were gone by night to God , and Allah rendered them from light .
"They say , "" When the man wakes his family from the night and claps , they write a book of the memories , Allah is a lot of memories . """
"VII: The forgiveness of sin, where he came in the honest Prophetic talk: ""God says to his angels: Look at my slave has abandoned me in the dark and the wrongful, the illusive, the illusive, the sleepless, testify that I forgave him."""
"Eighth : "" When the slave is delicious and sleepy in his eyes , the Lord will please the prayer of his night , Allah will have their angels and say : "" You see my slave this is delicious , and I have not imposed it , witness that I have forgiven him . """
Ninth: It's a white facial heir: Night prayer whitening face.
X: The wind is fancy, the night prayer is fancy, the apparently the physical smell is meant, and the relationship between the two may be revealed by scientific evolution in a while.
"(11) You bring the living: ""The man is to lie and deny his livelihood, said: How does he deny his livelihood?" "He said, ""No night prayer shall be forbidden, and if night prayer is forbidden.""" And he was expanded in his living , as he said , '
"(12) Good creation: ""The night prayer improves the face and the creation improves..."""
13: The night prayer is that she spends religion ;
"(Laughter) The truth is, ""The truth is to be taken to peace and go to them . "" So if one comes from the shit of the world and live in the equations of the Hereafter, his mundane concerns are still."
"VIEW: Visual clearness, as the imam, who was honestly peaceful said, ""Sight-sighted."""
"( Night prayer ) , "" The House of Nourana is a home , and the House of Nourana is a nourishment . "" "" The houses that pray at night by the night , and the B ( the Quran ) may be a bulb , and the stars of the sky light up the people of the earth . """
"It is the reason for the love of angels , as the Messenger of Allah said , "" Night prayer is the sickness of the Lord and the love of the angels . """
"Eighteenth: It's the reason for ""knowledge light."""
"IX: It's the reason for ""breaks."""
"Twenty: It's a worship that the devil hates. In the honourable talk." And the devil's hatred
"Twenty-first: It's a weapon on the enemies, ""Twenty-second, it's the reason for the prayers."""
"Twenty-third: It's the reason for ""Acception of Business."""
"Twenty-fourth: It's the reason for the prolongation of age, and the imam said, ""Satisfaction with peace"" in a specific conversation: ""Extending his age."""

"The 25th Jama is giving prestige to those who perform it , the prince of believers said : "" Allah has put five things in five places . """ And prestige in the night .

Imam as-Sadiq (AS) has said:

"The reward of every good action that a person with true faith performs has been mentioned in the Quran, except for Salatul Layl, since due to the importance (and high status) of it, Allah (SWT) has not explicitly mentioned it and has only said the following (in regards to it):

((Those who forsake their beds to cry unto their Lord in fear and hope, and spend out of that which We have bestowed upon them.))                                 

Surah as-Sajdah (32:16)
 

Allah (SWT) in explaining Salatul Layl and those who stay up during the night (doing Ibadaat) has said:

((Surely the rising by night is the firmest way to tread and the best corrective of speech.  Surely you have in the day time a long occupation.))                     Surah Muzzammil (73:6-7)
