Arabic (Original)
حَدَّثَنَا يَحْيَى عَنْ شُعْبَةَ حَدَّثَنَا قَتَادَةُ عَنْ أَنَسٍ عَنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ اعْتَدِلُوا فِي السُّجُودِ وَلَا يَبْسُطْ أَحَدُكُمْ ذِرَاعَيْهِ انْبِسَاطَ الْكَلْبِ.
English Translation
Yahya narrated to us, from Shu'bah: Qatadah narrated to us, from Anas, from the Messenger of Allah, peace and blessings be upon him, who said: "Be moderate in prostration, and let none of you spread his forearms out like a dog spreads its paws."
