‘Qiyam’ means standing and ‘Qiyam Al-Layl’ means standing in night. In the Islamic terminology, both terms refer to the voluntary night prayer, whose time extends from after `Isha’ (Night) prayer until dawn. Qiyam Al-Layl is also known as Tahajjud.
A widespread misconception is that Tahajjud is a different night prayer than Qiyam. The true is that there is only one voluntary night prayer known by different names.
The Excellence of Night Prayer
Numerous Prophetic narrations and Qura’nic verses mention the excellence of night prayer and the merit of those who perform it regularly. Allah the Almighty says:
O you who wraps himself [in clothing], arise [to pray] the night, except for a little – half of it – or subtract from it a little or add to it, and recite the Qur’an with measured recitation. (Al-Muzzammil 73:1-4)
It is reported that the Messenger of Allah (peace be upon him) said: “Allah, Our Lord, descends (in a manner befitting His Majesty) to the nearest heaven to us of this universe during the last third of the night and says: ‘Is there anyone to call upon Me so that I shall respond to him (fulfill his prayer). Is there anyone to ask of Me that I may grant his request. Is there anyone to seek My forgiveness so that I shall pardon him (and forgive his sins)’.” (Al-Bukhari and Muslim)
`A’ishah (may Allah be pleased with her) reported that the Prophet said: “The most beloved deeds to Allah are the most constant, even if they were little.” (Al-Bukhari and Muslim)
She said in another narration: “Do not ever stop praying Qiyam. The Prophet never ceased praying it. When he was sick or weak, he prayed sitting.” (Al-Bukhari and Muslim)
The Prophet also said: “You should pray Qiyam 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.” (At-Tirmidhi and Ahmad)
Abu Hurayrah (may Allah be pleased with him) reported that the Messenger of Allah said: “The best of prayer after those prescribed (i.e. obligatory prayer) is that in the depth of night.” (Muslim)
Abu Hurayrah (may Allah be pleased with him) also reported that the Messenger of Allah said: “May Allah have mercy on a man who wakes up at night, prays, and wakes his wife to pray; and if she refuses, he sprinkles water on her face. And may Allah have mercy on a woman who wakes up at night, prays, and wakes her husband to pray; and if he refuses, she sprinkles water on his face.” (Abu Dawud)
Again, the Prophet (peace be upon him) said: “Verily, there is one hour during the (entire) night when any Muslim (submitting to the Will of Allah the Almighty) may call upon Allah and request anything of Him, regardless of whether the matter be worldly or of the hereafter. Allah, the Almighty will grant and fulfill the request. This is the case every night.” (Muslim)
Those who regularly perform the night prayers are the righteous and are more deserving of Allah’s bounty and mercy. Allah says:
Indeed, the righteous will be among gardens and springs, accepting what their Lord has given them. Indeed, they were before that doers of good. They used to sleep but little of the night, and in the hours before dawn they would ask forgiveness. (Adh-Dhariyat 51: 15-18)
Allah says that those who do not possess these qualities cannot be treated as equal to those who possess them. He The Almighty says:
Is one who is devoutly obedient during periods of the night, prostrating and standing [in prayer], fearing the Hereafter and hoping for the mercy of his Lord, [like one who does not]? Say, “Are those who know equal to those who do not know?” Only they will remember [who are] people of understanding. (Az-Zumar 39: 9)
Etiquettes of Night Prayer
The following acts are Sunnah (recommended) for the one who wishes to perform the night prayers. Upon going to sleep, one should make the intention to perform the prayers. Abu Abu Ad-Darda’ (may Allah be pleased with him) related that the Prophet said: “Whoever goes to his bed with the intention of getting up and praying during the night, and sleep overcomes him until the morning comes, he will have recorded for him what he had intended, and his sleep will be a charity for him from his Lord.”(An-Nasa’i and Ibn Majah)
Upon waking, one should wipe one’s face, use a Miswaak (tooth stick), and make this supplication: “There is no god but You, Glory be to You, I seek forgiveness from You for my sins, and I ask for Your mercy. O Allah, increase my knowledge and let my heart not swerve after You have guided me, and bestow mercy upon me from Yourself. All praise be to Allah who has given us back life after our death and unto Him is the resurrection.”
Then, one should recite the last ten verses of chapter Aal-`Imran, then one should say, “O Allah, to You belongs the praise. You are the Light of the heavens and the earth and what is therein. And to You belongs the praise. You are the truth and Your promise is true. And the meeting with You is true. And the paradise is true. And the Fire is true. And the prophets are true. And Muhammad is true. And the Hour is true. O Allah, to You have I submitted. And in You have I believed. And in You have I put my trust. And to You have I turned. And by You I argue. And to You do I turn for my decisions. Forgive me of my former and latter sins, and those done in private and those done in public. You are Allah, there is no god besides You.”
One should begin the night prayer with two quick rak`ahs and then may pray whatever he wishes after that. `A’ishah said: “When the Prophet prayed during the late-night, he would begin his prayers with two quick rak`ahs.” (Muslim)
The Recommended Time for Night Prayer
The night prayer may be performed in the early part of the night, the middle part of the night, or the latter part of the night, but after the obligatory `Isha’ (Night) prayer.
Anas described the prayer of the Prophet as: “If we wanted to see him praying during the night, we could see him praying. If we wanted to see him sleeping during the night, we could see him sleeping. And sometimes he would fast for so many days that we thought he would not leave fasting throughout that month. And sometimes he would not fast (for so many days) that we thought he would not fast during that month.” (Al-Bukhari)
Commenting on this subject, Ibn Hajar said: “There was no specific time in which the Prophet would perform his night prayer, but he would do whatever was easiest for him.”
Best Time for Night Prayer
It is best to delay this prayer to the last third portion of the night. Abu Hurayrah reported that the Prophet said: “Our Lord descends to the lowest heaven during the last third of the night, inquiring: ‘Who will call on Me so that I may respond to him? Who is asking something of Me so I may give it to him? Who is asking for My forgiveness so I may forgive him?”‘ (Abu Dawud)
The Number of Rak`ahs (units of prayer) to be Performed during Night Prayer
The night prayer does not entail a specific number of rak`ahs which must be performed nor is there any maximum limit which has to be performed. It would be fulfilled even if one just prayed one rak`ah of Witr after the obligatory night prayer.
Samurah Ibn Jundub (may Allah be pleased with him) said: “The Messenger of Allah ordered us to pray during the night, a little or a lot, and to make the last of the prayer the Witr prayer.” (At-Tabarani and Al-Bazzar)
It is Preferable to pray eleven or thirteen Rak`ahs for Night Prayer
One may choose between praying them all together or to separate them. `A’ishah said: “The Messenger of Allah never prayed more than eleven rak`ahs, during Ramadan or otherwise. He would pray four rak`ahs, and don’t ask about how excellent they were or how lengthy they were. Then, he would pray four rak`ahs, and don’t ask about how excellent they were or how lengthy they were. Then, he would pray three rak`ahs. I asked: ‘O Messenger of Allah, do you sleep before praying Witr?’ He replied: ‘O `A’ishah, my eyes sleep but my heart does not sleep.”‘ (Al-Bukhari and Muslim)
`A’ishah said: “The prayer of the Messenger of Allah during the night would be ten rak`ahs and then he would make Witr with one rak`ah.”
