Narrated Anas:
حَدَّثَنَا مُسَدَّدٌ ، حَدَّثَنَا عَبْدُ الْوَارِثِ ، عَنْ عَبْدِ الْعَزِيزِ ، عَنْ أَنَسٍ ، قَالَ كَانَ أَكْثَرُ دُعَاءِ النَّبِيِّ صلى الله عليه وسلم " اللَّهُمَّ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً، وَفِي الآخِرَةِ حَسَنَةً، وَقِنَا عَذَابَ النَّارِ " .
The most frequent invocation of The Prophet (ﷺ) was: "O Allah! Give to us in the world that which is good and in the Hereafter that which is good, and save us from the torment of the Fire." (2.201)
