On first seeing the Kaaba
اللَّهُ أَكْبَرُ، لَا إِلَٰهَ إِلَّا اللَّهُ
Allahu Akbar. La ilaha illallah.
Allah is the Greatest. There is none worthy of worship except Allah. No specific wording from the Prophet ﷺ is established for this moment. Say the takbir, send salawat, and ask in your own words. The guidebook line “increase this House in honour…” is not a proven hadith.
Starting each circuit of Tawaf
بِسْمِ اللَّهِ وَاللَّهُ أَكْبَرُ
Bismillah, Allahu Akbar.
In the name of Allah, and Allah is the Greatest.
Between the Yemeni Corner and the Black Stone
رَبَّنَا آتِنَا فِي الدُّنْيَا حَسَنَةً وَفِي الْآخِرَةِ حَسَنَةً وَقِنَا عَذَابَ النَّارِ
Rabbana atina fid-dunya hasanah, wa fil-akhirati hasanah, wa qina ‘adhaban-nar.
Our Lord, give us good in this world and good in the Hereafter, and protect us from the punishment of the Fire.
Entering a mosque
اللَّهُمَّ افْتَحْ لِي أَبْوَابَ رَحْمَتِكَ
Allahumma iftah li abwaba rahmatik.
O Allah, open for me the gates of Your mercy.
