Narrated by:Jabir said
It was narrated that Jabir said:The Messenger of Allah (ﷺ) said: “When anyone of you prostrates let him be balanced in prostration, and not spread his arms as a dog does.”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا وَكِيعٌ، عَنِ الأَعْمَشِ، عَنْ أَبِي سُفْيَانَ، عَنْ جَابِرٍ، قَالَ قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ " إِذَا سَجَدَ أَحَدُكُمْ فَلْيَعْتَدِلْ، وَلاَ يَفْتَرِشْ ذِرَاعَيْهِ افْتِرَاشَ الْكَلْبِ " .
