أَخْبَرَنَا هَاشِمُ بْنُ الْقَاسِمِ ، وَسَعِيدُ بْنُ الرَّبِيعِ ، قَالَا : حَدَّثَنَا شُعْبَةُ ، عَنْ قَتَادَةَ ، قَالَ : سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ، يَقُولُ : قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ :" اعْتَدِلُوا فِي الرُّكُوعِ وَالسُّجُودِ، وَلَا يَبْسُطْ أَحَدُكُمْ ذِرَاعَيْهِ بِسَاطَ الْكَلْبِ "

Hashim bin Al-Qasim and Saeed bin Al-Rabi’ told us, saying: Shu’bah told us, on the authority of Qatada, he said: I heard Anas bin Malik, saying: He said: The Messenger of God, may God bless him and grant him peace: “Be moderate in bowing and prostrating, and do not let any of you spread out his arms like a dog’s rug.”
