The short answer: If you missed these prayers, you should make them up (qada) as soon as you remember, and sincerely repent. Missing prayers is a serious matter, but Allah is Most Forgiving, and He accepts the repentance of those who return to Him.
Why these prayers matter so much
The prayers you mentioned — Fajr and Asr especially — carry a special weight in Islam. The Prophet ﷺ said:
> "He who prays before sunrise and before sunset will not enter Hellfire."
> [Sahih Muslim 634]
This refers to Fajr (before sunrise) and Asr (before sunset). The scholars explain that being consistent with these two prayers is a sign of a soul that truly loves worship — because Fajr comes when sleep is most sweet, and Asr comes when you're busiest with worldly affairs. If you guard these two, you're more likely to guard the rest.
The Prophet ﷺ also warned:
> "Whoever abandons the Asr prayer, his deeds will be rendered worthless."
> [Sahih Bukhari 553]
This is a strong warning — not to scare you away, but to show how serious it is to neglect these prayers deliberately.
What you should do now
1. Pray them now, in order. Make up Fajr, then Dhuhr, then Asr — in their correct sequence. The majority of scholars (including the Hanafi, Maliki, Shafi'i, and Hanbali schools) agree that missed obligatory prayers must be made up.
2. Repent sincerely (tawbah). Turn to Allah with regret, resolve not to repeat it, and ask for His forgiveness. Allah says He forgives all sins for those who repent.
3. Don't despair. The fact that you're asking about this shows your heart is alive. That itself is a good sign.
A practical tip
The best way to avoid missing prayers is to set reminders. Your Al Muslim Plus app has a Prayer Times section with accurate timings for your location — you can use it to know exactly when each prayer enters, and plan your day around it. You can also enable notifications so you never miss Fajr or Asr again.
May Allah accept your prayers and keep you steadfast. If you have a specific situation (like oversleeping, or being in a place where you couldn't pray), feel free to share more and I can give more tailored guidance — and for complex cases, always consult a qualified scholar.
