If you look back, you'll see that every situation that Allah has brought you into, has either changed you, helped you grow, made you stronger, taught you a lesson, or made you a better person. Everything He does, has a purpose.
Prepare for the Day of Arafah from now.
Make your duas lists
Make your dhikr lists
Remember to wake up for tahajjud
Remember to FAST on that day
Remember to do istighfaar and read Quran between tahajjud and fajr and fajr till sunrise
