Arabic (Original)
حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ عَمْرٍو حَدَّثَنَا هِشَامٌ عَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اعْتَدِلُوا فِي السُّجُودِ وَلَا يَسْجُدْ أَحَدُكُمْ بَاسِطًا ذِرَاعَيْهِ كَالْكَلْبِ.
English Translation
Abd al-Malik ibn Amr told us: Hisham told us, from Qatada, from Anas, that the Prophet, peace and blessings be upon him, said: Be moderate in prostration, and let none of you spread his forearms out like a dog.
