وَبِالْأَسْحَارِ هُمْ يَسْتَغْفِرُونَ [Qur’an 51:18]
And in the hours before dawn, they were (found) asking (Allah) for forgiveness. [Qur’an 51:18]
A scholar of the past mentioned that some would use this aayah to show the merits of seeking forgiveness just before the start of Fajr time until Fajr time actually starts.
Another scholar of the past said al Hasan al Basri, from the pious people of the past, said this means seeking forgiveness for ones sins.
The Prophet (sal Allahu alaihi wa sallam) said: “The Lord descends every night to the lowest heaven when one-third of the night remains and says: ‘Who will call upon Me, that I may answer Him? Who will ask of Me, that I may give him? Who will seek My forgiveness, that I may forgive him?’”
[Sahih Al-Bukhari and Muslim]
Try to be from those that take advantage of this time, even if it’s only 5 minutes before Fajr especially when the nights are long! And success is from Allah alone!
