What is the ruling on not waking up for Dhuhr or Fajr prayer due to sleep, and what is the solution to this problem?

The time for Dhuhr ends with the entry of the time for Asr. Sleeping from after sunrise until the time for Dhuhr ends leads to missing the prayer, and all means must be taken to wake up for prayer, such as using multiple alarms or asking friends for help. Furthermore, sleeping early after Isha helps to avoid staying up late, which may lead to missing the prayer. It is not permissible for a Muslim to cause the loss of a fard (obligatory) prayer by staying up late, even if the late night activity is for a supererogatory act. If staying awake until sunrise conflicts with waking up for Dhuhr, then sleeping after Fajr is more appropriate to ensure performing the Dhuhr prayer.
