عَنْ عَبْدِ اللَّهِ بْنِ مَالِكٍ ابْنِ بُحَيْنَةَ رضي الله عنه:
أَنَّ النَّبِيَّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا صَلَّى فَرَّجَ بَيْنَ يَدَيْهِ حَتَّى يَبْدُوَ بَيَاضُ إِبْطَيْهِ.
[صحيح] - [متفق عليه] - [صحيح البخاري: 390]

Abdullah ibn Mālik ibn Buhaynah (may Allah be pleased with him) reported:
When the Prophet (may Allah's peace and blessings be upon him) prayed, he used to spread out his hands until the whiteness of his armpits would be visible.
[Authentic hadith] - [Narrated by Bukhari & Muslim] - [Sahih Bukhari - 390]
When prostrating, the Prophet (may Allah's peace and blessings be upon him) used to spread out his hands during Sujūd (prostration), keeping each hand away from its respective side like the two wings, until the skin color of his armpits would become visible. This is a form of exaggeration in distancing the arms and keeping them far from his sides.
