I heard the Messenger of Allah ﷺ say between the two corners: O Allah, bring us a blessing in this world and a blessing in the next and guard us from punishment of Hell.
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ مَا بَيْنَ الرُّكْنَيْنِ { رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ }
