The Mu'adhdhin Saying The Iqamah When The Imam Comes Out
Sunan an-Nasai
أَخْبَرَنَا الْحُسَيْنُ بْنُ حُرَيْثٍ، قَالَ حَدَّثَنَا الْفَضْلُ بْنُ مُوسَى، عَنْ مَعْمَرٍ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا أُقِيمَتِ الصَّلاَةُ فَلاَ تَقُومُوا حَتَّى تَرَوْنِي خَرَجْتُ " .
It was narrated from 'Abdullah bin Abi Qatadah that his father said: "The Messenger of Allah (S.A.W) said: 'When the Iqamah for prayer is said, do not stand up until you see that I have come out.'"
