[Machine] The passage describes the narration of Abu Bakr, Abdullah ibn Mas'ud, and Ibn Abbas, where Ibn Abbas stood to the left of the Prophet Muhammad ﷺ and then moved behind him until he stood to his right, resembling a proof (or evidence). This is because in the position of leading the prayer, he remained alone behind him and his prayer was not corrupted.
بَكْرٍ الصِّدِّيقِ وَعَبْدِ اللهِ بْنِ مَسْعُودٍ ؓ وَحَدِيثُ ابْنِ عَبَّاسٍ حَيْثُ وَقَفَ عَلَى يَسَارِ النَّبِيِّ ﷺ فَأَدَارَهُ مِنْ خَلْفِهِ حَتَّى جَعَلَهُ عَنْ يَمِينِهِ كَالْحُجَّةِ فِي هَذَا لِأَنَّهُ فِي حَالِ الْإِدَارَةِ بَقِيَ مُنْفَرِدًا خَلْفَهُ وَلَمْ تَفْسُدْ صَلَاتُهُ
