This tradition has also been reported through a different chain of narrators in a similar way. This version says:

“Until you see me that I have come out”.

Abu dawud said: No one except Ma’mar has narrated the words “that I have come out”. And the version transmitted by Ibn ‘Uyainah from Ma’mar does not mention the words “that I have come out”.

حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، حَدَّثَنَا عِيسَى، عَنْ مَعْمَرٍ، عَنْ يَحْيَى، بِإِسْنَادِهِ مِثْلَهُ قَالَ " حَتَّى تَرَوْنِي قَدْ خَرَجْتُ " . قَالَ أَبُو دَاوُدَ لَمْ يَذْكُرْ " قَدْ خَرَجْتُ " . إِلاَّ مَعْمَرٌ . وَرَوَاهُ ابْنُ عُيَيْنَةَ عَنْ مَعْمَرٍ لَمْ يَقُلْ فِيهِ " قَدْ خَرَجْتُ " .
