What Has Been Related About Being Balanced During Prostration
Jami at-Tirmidhi
حَدَّثَنَا مَحْمُودُ بْنُ غَيْلاَنَ، حَدَّثَنَا أَبُو دَاوُدَ، أَخْبَرَنَا شُعْبَةُ، عَنْ قَتَادَةَ، قَالَ سَمِعْتُ أَنَسًا، يَقُولُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " اعْتَدِلُوا فِي السُّجُودِ وَلاَ يَبْسُطَنَّ أَحَدُكُمْ ذِرَاعَيْهِ فِي الصَّلاَةِ بَسْطَ الْكَلْبِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
Anas narrated that : Allah'S Messenger Said: "Be Balanced In The Prostration, And Let One Of You Not Spread His Forearms (On The Ground) In The Salat Like The Spreading Of The Dog."
