Sleep is one of the signs of Allah: “And of His signs is your sleep by night and day” (Qur’an 30:23). It is also one of the pillars of health. According to US government survey data for 2024, about 30% of American adults sleep less than the recommended seven hours a night, and the picture is similar in many countries. For Muslims, waking for Fajr adds another reason to get sleep right.
How much sleep do adults need?
The American Academy of Sleep Medicine and the Sleep Research Society recommend that adults sleep seven or more hours a night on a regular basis. Regularly sleeping less is linked with weight gain, high blood pressure, diabetes, low mood and poorer concentration.
The Prophetic sleep routine
The Sunnah offers a routine that fits well with modern sleep science:
- Sleep early. The Prophet ﷺ disliked sleeping before Isha and talking after it (reported by al-Bukhari). Going to bed soon after Isha makes waking for Fajr much easier.
- Wind down with remembrance. Making wudu, reciting Ayat al-Kursi and the last three surahs, and lying on the right side create a calming bedtime ritual.
- Wake for Fajr and use the morning. The Prophet ﷺ prayed for blessing in the early morning for his community (reported by Abu Dawud and al-Tirmidhi). Morning light after Fajr is one of the strongest signals for setting your body clock.
- Take a short midday nap. Qailulah, a short rest around midday, can refresh you without harming night-time sleep if kept to 20–30 minutes.
When Fajr is very early
In summer at high latitudes Fajr can fall very early. Many people pray Fajr and then return to sleep for an hour or two; others take a longer qailulah. Both approaches can help you reach seven hours across the day. Consistency matters most.
Modern sleep thieves
- Screens: put phones away 30–60 minutes before bed, or at least use night mode and keep them out of reach.
- Caffeine: avoid tea, coffee and energy drinks after mid-afternoon.
- Heavy late meals: finish dinner two to three hours before bed.
- Irregular schedules: keep wake-up times similar at weekends.
When to seek help
Loud snoring with pauses in breathing, persistent insomnia, or severe daytime sleepiness can be signs of a sleep disorder. Speak to your doctor; effective treatments are available.
