What is the reward of the one who sits in voluntary prayer?

Question : The questioner says: Honorable Shaykh, what is the validity of the statement that if one becomes tired in the night prayer, he should sit and he gets half the reward? What is the evidence?

Answer : For the one performing voluntary prayer, it is permissible to pray standing, it is permissible to pray sitting, and it is permissible to pray while sitting. However, the reward of the one who sits, if he has no excuse, is half the reward of the one who stands. So, the one who prays tarawih who is unable to stand and prays sitting: he is asked whether it was his habit before this to pray standing. If it is said yes, we tell him he gets the reward of the one who stands, even if he is sitting. And if they say no, he is not consistent in this act, then it is not recorded for him.
