Ibn 'Abbas (رضي الله عنه) said:

Two little girls of Banu Hashim passed by and came to the Messenger of Allah (ﷺ) when he was praying, and held onto his knees, but he did not stop his prayer. Ibn 'Abbas said: An Ansari man and I passed by the Messenger of Allah (ﷺ) when he was praying, and we were riding a donkey, and we came and joined the prayer.
