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).
This is based on multiple hadiths about supplications during the night, out of which is one about reciting during the night the last two verses of Surat al-Baqara, and Surat al-Ikhlās.
