The Prophet PBUH used to say between the Yemeni corner and the black stone:
﴿رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ﴾
Rabbanā ātinā fī ad-dunyā ḥasanatan wa fī l-ʾākhirati ḥasanatan wa qinā ʿadhāba an-nār
Our Lord, give us what is good in this world and what is good in the Hereafter, and protect us from the punishment of the Fire.
