Is it ok to pray while wearing a shirt having a small picture of lacoste (animal) on the left part of my chest?

All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.

Performing prayer while wearing a dress with a picture of a living soul on it is forbidden for the Hadeeth reported on the authority of Anas, may Allah be pleased with him, who said: “‘Aa’ishah had a Qiram (a colored curtain) with which she had screened one side of her home. The Prophet said: “Take away this Qiram of yours, as its pictures are still displayed in front of me during my prayer (i.e., they divert my attention from the prayer).”

As long as the Prophet prevented hanging a curtain that had pictures, then, with greater reason, wearing it becomes forbidden whether it is worn during prayer or not. However, even though wearing such a cloth is forbidden, the prayer is valid.

Allah knows best.
