Should he put the back legs of the chair in line with the row (when praying)?

If a person prays sitting on a chair in the mosque, should he put the back legs or the front legs of the chair in line with the other worshippers’ feet?

Praise be to Allah, and blessings and peace be upon the Messenger of Allah:

We put this question to Shaykh Muhammad ibn Saalih ibn ‘Uthaymeen, may Allaah preserve him, who answered as follows:

He should put the back legs of the chair in line with the other worshippers’ feet.

Question:

But then when he stands, he will be in front of the others

Answer:

He isn’t standing, (so he should put) his back in line with the feet of the other worshippers. And Allaah knows best.
