Vitr namaz mein dua qunoot na yaad ho to kia karna hai?
بسم الله الرحمن الرحيم
(Fatwa: 1028/646/H=1432)
He should read any dua mentioned in Quran and hadith, for example:
رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ .
Or he should read رب اغفرلى three times or more.
Allah knows Best!
