Sunan an-Nasa'i 1103

Be moderate in prostration, and let none of you spread his forearms on the ground like a dog

Anas ibn Mālik (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Be moderate in prostration, and let none of you spread his forearms on the ground like a dog."

"‏ اعْتَدِلُوا فِي السُّجُودِ وَلاَ يَبْسُطْ أَحَدُكُمْ ذِرَاعَيْهِ انْبِسَاطَ الْكَلْبِ ‏"

The Messenger of Allah (ﷺ) said: “When anyone of you prostrates let him be balanced in prostration, and not spread his arms as a dog does.”

"‏ إِذَا سَجَدَ أَحَدُكُمْ فَلْيَعْتَدِلْ، وَلاَ يَفْتَرِشْ ذِرَاعَيْهِ افْتِرَاشَ الْكَلْبِ ‏"

The Prophet (ﷺ) said, "Do the prostration properly and do not put your forearms flat with elbows touching the ground like a dog. And if you want to spit, do not spit in front, nor to the right for the person in prayer is speaking in private to his Lord."

اعْتَدِلُوا فِي السُّجُودِ، وَلاَ يَبْسُطْ ذِرَاعَيْهِ كَالْكَلْبِ، وَإِذَا بَزَقَ فَلاَ يَبْزُقَنَّ بَيْنَ يَدَيْهِ وَلاَ عَنْ يَمِينِهِ، فَإِنَّهُ يُنَاجِي رَبَّهُ ‏"

Narrated by Anas ibn Mālik

when one of you prostrates himself, he should not stretch out his forearms( on the ground) like a dog and he should join both of his thighs.

إِذَا سَجَدَ أَحَدُكُمْ فَلاَ يَفْتَرِشْ يَدَيْهِ افْتِرَاشَ الْكَلْبِ وَلْيَضُمَّ فَخِذَيْهِ ‏"
