Ok I did some research on this

and here are some Sunan and some good practises that will help people to do Qiyam al-Layl Insha'allah.
First of all, Qiyam al-Layl is Sunnah Mu'akkadah. Rasulullah said
“You should pray qiyaam al-layl, for it is the habit of the righteous people who came before you, and it will bring you closer to your Lord, expiate for bad deeds, prevent sin, and expel disease from the body.” (Reported by al-Tirmidhi and Ahmad).
And he said
"The best of prayers after the prescribed prayers is qiyaam al-layl.”
From some of the Sunan is going to sleep early and preferrably right after Isha'.
Narrated by Abu Barzah al-Aslami (may Allaah be pleased with him) who said that the Prophet (peace and blessings of Allaah be upon him) used to prefer to delay ‘Ishaa’, and he did not like to sleep before it or talk after it. (Reported by al-Bukhaari).
Ibn Raafi’ said: “ ‘Umar ibn al-Khattaab (may Allaah be pleased with him) used to wave his stick at the people when darkness fell, and would say,
‘Get up and go, may Allaah help you to pray qiyaam at night!’”
Also it's good Sunnah to take a nap during the day so that it will be easier to wake up at night. This nap should be a light nap taken after Dhuhr and it's called 'Qayloolah' Anas (may Allaah be pleased with him) reported that the Prophet (peace and blessings of Allaah be upon him) said:
“Take a nap, for the shayaateen do not take naps.”Reported by al-Tabaraani. Al-Saheehah,
Ishaaq ibn ‘Abd-Allaah said:
“Taking a nap is one of the deeds of good people. It revitalizes the heart and helps one to pray qiyaam al-layl.”
Also, eating lightly helps keep a person more alert and thus helps him to feel
less lazy at waking up for Qiyam al-Layl ( Hmmm....I know a person in particular who likes to eat.....maybe I should tell him this ;D )
Sufyaan al-Thawri said:
“You should eat little, so that you will be able to pray qiyaam al-layl.”
Wahb ibn Munbih said:
“There is no son of Adam dearer to his shaytaan than the one who eats and sleeps a lot.”
A Person who fights against his nafs and strives to do Qiyaam al-Layl is greatly rewarded. Rasulullah said
"“When a man from my ummah gets up to pray at night, striving against his own self to get up and purify himself, there are knots on him. When he washes his hands in wudoo’, one knot is undone. When he washes his face, another knot is undone. When he wipes his head another knot is undone. When he washes his feet, another knot is undone. Then Allaah says to those who are veiled (in the Unseen): ‘Look at this slave of Mine, he is striving against his own self and asking of Me. Whatever My slave asks of Me shall be his.” (Reported by Ahmad and Ibn Hibaan)
Also it's Sunnah that when one wakes up for Qiyaam al-Layl that he should first brush his teeth with Siwaak. I can't remember the Sahaabi right now :-\ but I think it is Hudhaifah ibn al-Yamaan, He said that
when Rasulullah used to wake up for Qiyaam al-Layl he would first brush his teeth with Siwaak.
It's Sunnah also to make Qiyaam al-Layl towards the end part of the night. Aishah narrated that
Rasululllah used to sleep in the beginning of the night and wake up and make Qiyaam towards the end of it
When Rasulullah used to make Qiyaam, his first two Rak'aat used to be light and short. Aishah said
" When Rasulullah used to wake up for Qiyaam he would begin his prayers with two light Rak'ahs"
Also, if whilst one is praying one feels sleepy, he should lie down and rest until the sleep goes away. Rasulullah said
" If one of you feels sleepy whilst praying, then let him rest/sleep until the sleepiness goes, For it might be that if one of you prays whilst he is sleepy then he might not realize what he is saying and thus curse himself "
I hope this is satisfactory for you Bro Dhulqarnaen?:rollseyes
Ok so the next question will be :
What Is the Sunnah when serving others something to Drink?
