Does one who prays sitting due to illness receive the reward of one who prays standing?

Question:
May Allah reward you. Honorable Shaykh, regarding the tarawih prayer, if it is difficult for me, and I have had surgery and have a chair, do I pray on the chair? And is the reward the same?

Answer:
Yes, pray on the chair, and the reward is complete, if Allah wills; because you are excused in this. The Messenger (peace and blessings be upon him) said: The sick person prays standing, and if he cannot, then sitting, and if he cannot, then on his side, and in a narration: if he cannot, then lying on his back with his feet toward the qiblah. Fear Allah as much as you are able. You have, if Allah wills, the reward of the one who stands; because you did not leave standing except for an excuse. Yes.
