أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا عَبْثَرٌ، عَنِ الأَعْمَشِ، عَنِ الْمُسَيَّبِ بْنِ رَافِعٍ، عَنْ تَمِيمِ بْنِ طَرَفَةَ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ خَرَجَ عَلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم وَنَحْنُ رَافِعُو أَيْدِينَا فِي الصَّلاَةِ فَقَالَ " مَا بَالُهُمْ رَافِعِينَ أَيْدِيَهُمْ فِي الصَّلاَةِ كَأَنَّهَا أَذْنَابُ الْخَيْلِ الشُّمُسِ اسْكُنُوا فِي الصَّلاَةِ " .
Qutaybah ibn Sa‘id reported to us, saying: ‘Abthar reported to us, from al-A‘mash, from al-Musayyab ibn Rafi‘, from Tamim ibn Tarafah, from Jabir ibn Samurah, who said: The Messenger of Allah (ﷺ) came out to us while we were raising our hands during the prayer. He said, “Why are they raising their hands in prayer as though they were the tails of unruly horses? Be still during the prayer.”
Translation notes
The simile describes al-khayl al-shumus, restless or unruly horses.
