Sunan an-Nasa'i, Volume 1, Book 7, Hadith 688 (DarusSalam)

It was narrated from 'Abdullah bin Abi Qatadah that his father said: "The Messenger of Allah 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 ‏" ‏ ‏.‏
