Maimuna · The Book of Prayers

When the Messenger of Allah (ﷺ) prostrated himself, if a lamb wanted to pass between his arms, it could pass.

When the Messenger of Allah (ﷺ) prostrated himself, he spread his arms, i. e. he separated them so much that the whiteness of his armpits became visible from behind and when he sat (for Jalsa) he rested on his left thigh.

When the Messenger of Allah (ﷺ) prostrated, he kept his hands so much apart from each other that when it was seen from behind the armpits became visible. Waki' said: That is their whiteness.

The Messenger of Allah (ﷺ) said prayer and I (lay) opposite to him while I was in menses. Sometimes his clothes touched me when he prostrated.
