Arabic (Original)
حَدَّثَنَا وَكِيعٌ حَدَّثَنَا جَعْفَرُ بْنُ بُرْقَانَ عَنْ يَزِيدَ بْنِ الْأَصَمِّ عَنْ مَيْمُونَةَ قَالَتْ كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا سَجَدَ جَافَى حَتَّى يَرَى مَنْ خَلْفَهُ بَيَاضَ إِبْطَيْهِ.
English Translation
Waki' told us: Ja'far bin Burqan told us, from Yazid bin al-Asamm, from Maymunah, who said: "The Messenger of Allah, peace and blessings be upon him, when he prostrated, would spread his arms away from his sides until the one behind him could see the whiteness of his armpits."
