حَدَّثَنَا مُسْلِمُ بْنُ إِبْرَاهِيمَ حَدَّثَنَا شُعْبَةُ عَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اعْتَدِلُوا فِي السُّجُودِ وَلَا يَفْتَرِشْ أَحَدُکُمْ ذِرَاعَيْهِ افْتِرَاشَ الْکَلْبِ
سنن ابودوٗد · Hadith 897
Anas reported the Messenger of Allah ﷺ as saying; Adopt a moderate position when prostrating yourselves, and see that none of you stretches out his forearms (on the ground) like a dog.
