Anas narrated that :
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 .
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."
