Arabic (Original)
حَدَّثَنَا ابْنُ أَبِي عَدِيٍّ وَعَبْدُ الْوَهَّابِ الْخَفَّافُ عَنْ حُمَيْدٍ عَنْ قَتَادَةَ عَنْ أَنَسٍ أَنَّ نَبِيَّ اللَّهِ عَلَيْهِ الصَّلَاة وَالسَّلَامُ قَالَ اعْتَدِلُوا فِي السُّجُودِ وَلَا يَفْتَرِشْ أَحَدُكُمْ ذِرَاعَيْهِ كَالْكَلْبِ.
English Translation
Ibn Abi Adiyy and Abd al-Wahhab al-Khaffaf narrated to us from Humayd, from Qatadah, from Anas: that the Prophet of Allah, peace and blessings be upon him, said, "Be moderate in prostration, and let none of you spread out his forearms like a dog."
