A similar tradition has also been transmitted by Ibrahim and al-Sha’bi from the Prophet (ﷺ) through a different chain of narrators. But this version does not mention the words:

He called the witnesses who testified.

حَدَّثَنَا وَهْبُ بْنُ بَقِيَّةَ، عَنْ هُشَيْمٍ، عَنْ مُغِيرَةَ، عَنْ إِبْرَاهِيمَ، وَالشَّعْبِيِّ، عَنِ النَّبِيِّ صلى الله عليه وسلم نَحْوَهُ لَمْ يَذْكُرْ فَدَعَا بِالشُّهُودِ فَشَهِدُوا ‏.‏
