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)  

كَانَ أَكْثَرُ دُعَاءِ النَّبِيِّ ﷺ اللَّهُمَّ رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ
