BAYHAQI 2707:
from ʿUbaydullāh b. ʿAbdullāh b. Aqram al-Khuzāʿī from his father —
[Machine] "He was with his father in the valley of Namarah when a caravan passed by them. They moved aside from the road, and my father told me to stay hidden until I get closer to those caravans so that I can ask the Messenger of Allah, ﷺ . So, I approached until the prayer was established, and behold, the Messenger of Allah, ﷺ , was among them. I looked at the armpits of the Messenger of Allah, ﷺ , every time he prostrated. Ya'qub said, 'He said so from Namarah, and the correct one is Sumrah.' He made an error in it just as Ibn Mubarak did."
البيهقي ٢٧٠٧:
عن عبيد الله بن عبد الله بن اقرم الخزاعي عن أبيه —
أَنَّهُ كَانَ مَعَ أَبِيهِ بِالْقَاعِ مِنْ نَمِرَةَ فَمَرَّ عَلَيْهِمْ رَكْبٌ فَأَنَاخُوا بِنَاحِيَةِ الطَّرِيقِ فَقَالَ لِي أَبِي كُنْ فِي بَهْمِكَ حَتَّى أَدْنُوَ مِنْ هَؤُلَاءِ الرَّكْبِ أُسَائِلُهُ قَالَ فَدَنَا وَدَنَوْتُ حَتَّى أُقِيمَتِ الصَّلَاةُ فَإِذَا رَسُولُ اللهِ ﷺ فِيهِمْ فَكُنْتُ أَنْظُرُ إِلَى عُفْرَتَيْ إِبِطَيْ رَسُولِ اللهِ ﷺ كُلَّمَا سَجَدَ قَالَ يَعْقُوبُ هَكَذَا قَالَ مِنْ نَمِرَةَ وَالصَّحِيحُ ثَمِرَةُ أَخْطَأَ فِيهِ كَمَا أَخْطَأَ فِيهِ ابْنُ الْمُبَارَكِ أَيْضًا
