When the Prophet ﷺ prostrated himself, he kept his arms so far away from his sides that if a lamb had wanted to pass under his arms, it could have done so.
أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا سَجَدَ جَافَى بَيْنَ يَدَيْهِ حَتَّى لَوْ أَنَّ بَهْمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدَيْهِ مَرَّتْ
When the Prophet ﷺ prostrated he would hold his arms out from his sides so that if a lamb wanted to pass beneath his arms it would be able to do so.
أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا سَجَدَ جَافَى يَدَيْهِ حَتَّى لَوْ أَنَّ بَهْمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدَيْهِ مَرَّتْ
It was narrated from Maimunah that when the Prophet ﷺ prostrated, he would hold his forearms away from his sides, such that if a lamb wanted to pass under his arms, it would be able to do so.
أَنَّ النَّبِيَّ ﷺ كَانَ إِذَا سَجَدَ جَافَى يَدَيْهِ فَلَوْ أَنَّ بَهْمَةً أَرَادَتْ أَنْ تَمُرَّ بَيْنَ يَدَيْهِ لَمَرَّتْ
[Machine] When the Messenger of Allah ﷺ used to prostrate, a sparrow would want to pass between his hands and fly away.
كَانَ رَسُولُ اللهِ ﷺ إِذَا سَجَدَ وَثَمَّ بَهْمَةٌ أَرَادَتْ أَنْ تَمُرَّ بَيْنَ يَدَيْهِ تَجَافَى
[Machine] The Messenger of Allah ﷺ used to prostrate so long that if a goat wanted to pass underneath his hands, it could.
كَانَ رَسُولُ اللهِ ﷺ «إِذَا سَجَدَ جَافَى حَتَّى لَوْ أَنَّ بَهِيمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدَيْهِ مَرَّتْ»
When the Prophet ﷺ prostrated himself, he kept his arms so far away from his sides that if a lamb had wanted to pass under his arms, it could have done so. (Using translation from Abū Dāʾūd 898)
أَنَّ النَّبِيَّ ﷺ كَانَ «إِذَا سَجَدَ جَافَى يَدَيْهِ حَتَّى لَوْ أَنَّ بَهْمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدَيْهِ لَمَرَّتْ»
"كَانَ رَسُولُ اللهِ ﷺ إِذَا سَجَدَ تَجَافَى حَتَّى لَوْ أَنَّ بَهِيمَةً أَرَادَتْ أَنْ تَمُرَّ تَحْتَ يَدِهِ مَرَّتْ".
