I don’t recall saying that it is a bid’ah.

There is a hadeeth but it is not authentic. Some scholars like Imam Ahmed says that it is recommended to draw a line when there is no Sutra to pray to.

The Sunnah is to put an object that is about a foot high to pray to

You had mentioned somewhere that it is a bid’ah to draw lines and to have lines in the musjid. May you please explain that for me again, or direct me to the video or post you talked about it in. jazakallah khair.
