Dua Between Adhan and Iqamah

لَا إِلَهَ إِلَّا اللَّهُ وَحْدَهُ لَا شَرِيكَ لَهُ لَهُ الْمُلْكُ وَلَهُ الْحَمْدُ وَهُوَ عَلَى كُلِّ شَيْءٍ قَدِيرٌ

“There is no deity except Allah alone, with no partner. To Him belongs all sovereignty and praise, and He is over all things competent.”

La ilaha illallahu wahdahu la sharika lahu, lahul-mulku wa lahul-hamdu wa huwa 'ala kulli shay'in qadeer

— Sahih al-Bukhari 6403
