What is the ruling on the Asr prayer performed a short time before the Maghrib adhan, taking into account the noble Hadith: "Whoever catches one rak'ah of Asr before the sun sets, has caught Asr"? And what are the precise times for sunrise and sunset, the end time of the Maghrib prayer (disappearance of twilight), and the Dhuhr prayer time?

If you instruct your mother to wake you for the Asr prayer and she fails to do so, you are excused. Pray when you wake up during the necessary time, and there is no sin upon you. Prayer times are known by cosmic signs. It is not possible to determine the exact minute of sunrise and sunset, as sunrise begins with the appearance of its eyebrow. There is a difference of opinion regarding the end of the preferred time for Maghrib; what is considered is the disappearance of the twilight, not 45 minutes. The beginning of the preferred time for Dhuhr is from the sun's zenith until the shadow of everything becomes like its length, not from the adhan (definition).
