Arabic (Original)
حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا سُفْيَانُ عَنِ الْأَعْمَشِ عَنْ أَبِي سُفْيَانَ عَنْ جَابِرٍ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا سَجَدَ أَحَدُكُمْ فَلْيَعْتَدِلْ وَلَا يَفْتَرِشْ ذِرَاعَيْهِ افْتِرَاشَ الْكَلْبِ.

Abd al-Razzaq told us, Sufyan informed us, from al-A'mash, from Abu Sufyan, from Jabir, who said: The Messenger of Allah, peace and blessings be upon him, said: "When one of you prostrates, let him be moderate and not spread his forearms out as a dog spreads its forelegs."
