we bear witness that THERE IS NO GOD TO WORSHIP EXCEPT ALLAAH and MUHAMMAD is His MESSENGER and SLAVE
Many people having a misconception that if they can turn on alarm they can wake up for fajr, but mostly they fail. I have received many complaints from Muslims around me that they are able to manage prayers in Day but they are unable to wake up at fajr.
I will try to suggest from Book of ALLAAH and Hadith of His Messenger, InshaALLAAH
Our open Enemy Shaitan always trys to make you sleep so that you should not wake up for fajr prayer
Satan ties knots in your head while you sleep —
Sahih Bukhari Volume 4, Book 54, Number 491:
Narrated Abu Huraira: Allah’s Apostle said, “During your sleep, Satan knots three knots at the back of the head of each of you, and he breathes the following words at each knot, ‘The night is, long, so keep on sleeping.
So, this is one of reasons why you are not able to wake up for fajr
But if you do these below with firm Imaan, InshaALLAAH, you will able to defeat Shaitan and can wake up for fajr.
Sleeping In the State of Wudu
the Prophet (peace and blessings of Allaah be upon him) said: “When you go to bed, do wudoo’ as for prayer.”
(Narrated by al-Bukhaari, 247; Muslim 2710).
This is the virtue of this act
Angels will supplicate for him for those who sleep in Wudu
Ibn Umar reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever goes to sleep in a state of purity will have an angel over his head and he will not awaken until the angel says: O Allah, forgive your servant for he has slept with ablution.”

Reciting Ayat al-Kursi before sleeping
Narrated Abu Huraira: Prophet Muhammad salallahu alaihi wasallam ordered me to guard the Zakat revenue of Ramadan. Then somebody came to me and started stealing of the foodstuff. I caught him and said, “I will take you to Allah’s Apostle!” Then Abu Huraira described the whole narration and said: That person said (to me), “Please don’t take me to Allah’s Apostle and I will tell you a few words by which Allah will benefit you. WHEN YOU GO TO YOUR BED, RECITE AYATUL KURSI, (2.255) FOR THEN THERE WILL BE A GUARD FROM ALLAH WHO WILL PROTECT YOU ALL NIGHT LONG, AND SATAN WILL NOT BE ABLE TO COME NEAR YOU TILL DAWN.” When the Prophet heard the story he said (to me), “He (who came to you at night) told you the truth although he is a liar; and it was Satan.”
Sahih Al-Bukhari – Book 61 Hadith 530
If you do all these acts InshaALLAAH you will be able to wake up for fajr easily as prophet(peace & blessings of ALLAAH be upon him)
If that person wakes up and celebrates the praises of Allah, then one knot is undone, and when he performs ablution the second knot is undone, and when he prays, all the knots are undone, and he gets up in the morning lively and gay, otherwise he gets up dull and gloomy. ”
Sahih Buhari– Volume 4, Book 54, Number 491
So as Prophet said, when you wake up celebrate the praises of ALLAAH that is just “Remember Dua of waking up”. Most importantly seek ALLAAH’s refuge when you wake up by reciting Surah Falaq & an-Nas, because Shaitan will try to make you to sleep again.
And make Wudu and there you Go. You are ready for fajr. Make this process a habit. Don’t let Shaitan overcome you.
And let not the Shaitan prevent you; surely he is your open enemy.
You should over come shaitan
So lose not heart, nor fall into despair: For ye must gain mastery if ye are true in Faith (Qur’an-3/139)
All Praises for ALLAAH
ALLAAH knows best
