Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا شُعْبَةُ عَنْ قَتَادَةَ عَنْ أَنَسٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ اعْتَدِلُوا فِي السُّجُودِ وَلَا يَبْسُطْ أَحَدُكُمْ ذِرَاعَيْهِ انْبِسَاطَ السَّبُعِ.
English Translation
Waki' told us, Shu'bah told us, from Qatadah, from Anas, who said: The Messenger of God, peace and blessings be upon him, said, "Be moderate in prostration, and let none of you spread his forearms out like the spreading of a beast of prey."
