Translation:

219. And thy movements among those who prostrate themselves.

Notes (Tafseer)

3235. Literally, the standing and prostration are postures in Muslim prayer: the holy Prophet was equally earnest, sincere, and zealous in prayer for himself and for all his people. The Prophet's behaviour was exemplary in all the turns of fortune, and however foolish men may cavil, his purity and uprightness are fully known to Allah.
