when the prophet ﷺ became seriously ill, we prayed behind him while he was sitting and Abu Bakr was calling “Allah is most great “ to cause the people to hear the TAKBIR. Then he (the narrators) narrated the rest of the tradition.
اشْتَكَى النَّبِيُّ ﷺ فَصَلَّيْنَا وَرَاءَهُ وَهُوَ قَاعِدٌ وَأَبُو بَكْرٍ يُكَبِّرُ لِيُسْمِعَ النَّاسَ تَكْبِيرَهُ ثُمَّ سَاقَ الْحَدِيثَ
[Machine] He said, "The Messenger of Allah ﷺ complained, so we prayed behind him while he was sitting, and Abu Bakr raised his voice in takbeer, and he turned to us and saw us standing, so he gestured to us and mentioned the rest of the narration."
أَنَّهُ قَالَ اشْتَكَى رَسُولُ اللهِ ﷺ فَصَلَّيْنَا وَرَاءَهُ وَهُوَ قَاعِدٌ وَأَبُو بَكْرٍ ؓ يُكَبِّرُ يُسْمِعُ النَّاسَ تَكْبِيرَهُ قَالَ فَالْتَفَتَ إِلَيْنَا فَرَآنَا قِيَامًا فَأَشَارَ إِلَيْنَا وَذَكَرَ بَاقِي الْحَدِيثِ
