أَخْبَرَنَا سُوَيْدُ بْنُ نَصْرٍ، قَالَ أَنْبَأَنَا عَبْدُ اللَّهِ بْنُ الْمُبَارَكِ، عَنْ سُفْيَانَ، عَنْ عَاصِمِ بْنِ كُلَيْبٍ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ الأَسْوَدِ، عَنْ عَلْقَمَةَ، عَنْ عَبْدِ اللَّهِ، قَالَ أَلاَ أُخْبِرُكُمْ بِصَلاَةِ، رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ فَقَامَ فَرَفَعَ يَدَيْهِ أَوَّلَ مَرَّةٍ ثُمَّ لَمْ يُعِدْ .
It was narrated from 'Alqamah, that Abdullah said:
"Shall I not tell you about the prayer of the Messenger of Allah (ﷺ)? He stood and raised his hands the first time and then he did not do that again."
