“I heard Anas bin Malik say: ‘The Mu ’adh-dhin would call the Adhan during the time of the Messenger of Allah ﷺ, and one would think that it was the Iqamah because there were so many people who stood and performed the two Rak’ah before the Maghrib.” (Using translation from Ibn Mājah 1163)  

أحمد:١٤٠٠٨ – حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ عَنْ عَلِيِّ بْنِ زَيْدٍ قَالَ

سَمِعْتُ أَنَسًا يَقُولُ إِنْ كَانَ الْمُؤَذِّنُ لَيُؤَذِّنُ عَلَى عَهْدِ رَسُولِ اللهِ ﷺ فَنُرَى أَنَّهَا الْإِقَامَةُ مِنْ كَثْرَةِ مَنْ يَقُومُ فَيُصَلِّي الرَّكْعَتَيْنِ قَبْلَ الْمَغْرِبِ
