Can we read morning duas after fajar prayer and can we read evening duas after maghrib prayer ?
There is no definitive answer on the preferred time of morning and evening supplications, as there is a scholarly difference of opinions. Whichever opinion you decide to follow will be fine.
The first opinion is:
- Morning supplications start from Fajr adhān time till sunrise.
- Evening supplications start from 'Asr adhān time till sunset.
This is based on the following verse:
فَاصْبِرْ عَلَىٰ مَا يَقُولُونَ وَسَبِّحْ بِحَمْدِ رَبِّكَ قَبْلَ طُلُوعِ الشَّمْسِ وَقَبْلَ الْغُرُوبِ
So be patient, [O Muhammad], over what they say and exalt [ Allah ] with praise of your Lord before the rising of the sun and before its setting,
and additionally on the verse:
فَاصْبِرْ إِنَّ وَعْدَ اللَّهِ حَقٌّ وَاسْتَغْفِرْ لِذَنبِكَ وَسَبِّحْ بِحَمْدِ رَبِّكَ بِالْعَشِيِّ وَالْإِبْكَارِ
So be patient, [O Muhammad]. Indeed, the promise of Allah is truth. And ask forgiveness for your sin and exalt [ Allah ] with praise of your Lord in the evening and the morning.
The second opinion is:
- Morning supplications extend till Dhuha (about a half-hour before Dhuhr adhān time).
- Evening supplications extend till one-third of the night (one-third between 'Isha and Fajr adhān times).
