وَيُصَلِّي الْإِمَامُ بِالنَّاسِ الْمَغْرِبَ وَالْعِشَاءَ بِأَذَانٍ وَإِقَامَةٍ.
Translation: The imam leads the people in Maghrib and Isha with one adhan and one iqamah.
In al-Quduri’s Hanafi sequence, pilgrims combine Maghrib and Isha at Muzdalifah. His wording explicitly prescribes one adhan and one iqamah. They remain two distinct obligatory prayers.
Do not confuse this with Dhuhr–Asr at Arafat, where the text specifies one adhan and two iqamahs. The two sets of rites have different described calls.
