Abdullah bin Malik says that once Sayyiduna Ibn Umar (may Allah be pleased with them both) led the Maghrib and Isha prayers at Muzdalifah with a single Iqamah. Abdullah bin Malik asked: O Abdur Rahman! What kind of prayer is this? He replied: I have performed these prayers at this place with a single Iqamah along with the Noble Prophet (peace and blessings be upon him).
