Tirmidhi

Commentary:
1:
Today, the entire Ummah of Muhammad (sallallahu alayhi wa sallam), all its imams and all their followers, are so greatly deprived of this immense reward and the blessings of the early part of the day. Just consider this hadith to realize it. Except as Allah wills. O Allah, make us among them.

Benefits and Issues:
Benefit: This narration is weak in its chain of transmission.
However, being granted the ability to remember Allah is a great virtue and blessing.
And delivering or listening to admonition from the Qur’an and Sunnah is also included in the meaning of the remembrance of Allah.
Furthermore, the time from true dawn (fajr sadiq) until sunrise, and likewise from ‘asr until sunset, is the most excellent and precious time for drawing near to Allah.
It is stated: (So be patient over what they say and glorify the praises of your Lord before the rising of the sun and before its setting)
However, some scholars have also considered it to be hasan (acceptable).

Benefits:
From the mentioned hadith, it is understood that the time from Fajr until sunrise and from the Asr prayer until sunset is beneficial for the remembrance of Allah (dhikr).
And in the Noble Qur’an, there is encouragement for abundant remembrance during this period.
As the divine command states:
«يَا أَيُّهَا الَّذِينَ آمَنُوا اذْكُرُوا اللَّـهَ ذِكْرًا كَثِيرًا ٭ وَسَبِّحُوهُ بُكْرَةً وَأَصِيلًا» [33-الأحزاب:41]
“O believers! Remember Allah abundantly and glorify Him morning and evening.”
