Chapter 42 The Mu'adhdhin Saying The Iqamah When The Imam Comes Out
باب إِقَامَةِ الْمُؤَذِّنِ عِنْدَ خُرُوجِ الإِمَامِ
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.'"
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 " .
