Selam Aleykum,

I want to share tips with you that will in sha Allah make waking up for fajr easier.

1. Don't go too late to bed

Your journey to waking up easy starts here:
As you now we have different sleep cycles. If you sleep too late at night, the risk of sleeping in the deepest sleep cycle is way higher and waking up will be hard.

2. Know the benefit of waking up for fajr

"The two sunnah cycles of prayer preceding Fajr prayer are better than this world and all that it contains.โ€ - Prophet Muhammad (saw.)
โ€œWhoever prays the Fajr prayer, he or she is then under Allahโ€™s protection. So beware, O son or daughter of Adam, that Allah does not call you to account for being absent from His protection for any reason.โ€

Read or watch videos on YouTube on how important this prayer is for your iman.

3. Know the consequences of missing the fair prayer

If you missed fajr prayer don't think that Allah will not forgive you (!! ) and pray it anyway but know that missing your prayer is a sin.

4. Set more than one alarm

For instance if you did not hear an alarm it is very useful to have more alarms. (and don't press the snooze button!)

5. Your niyah (intention) is very important

If your niyah is coming from your heart Allah will help you to wake up everyday.

6. Ask your parents/siblings to wake you up

7. Nothing will happen if you don't ask Allah for help

You can not wake up without the help of Allah.
I like to make dua at the isha prayer that may Allah will wake me up to fajr the next morning.
When I am forgetting this dua I often sleep so long that there is no time for fajr left.

Search the reason why it is so difficult for you to wake up and pray that Allah will make it easier for you.
