“I asked the Prophet (Sallallaahu ‘alaihi wasallam) about the prayer of a person while sitting.
He (Sallallaahu ‘alaihi wasallam) said:
‘It is better for one to pray standing; and whoever prays sitting gets half the reward of that who prays while standing; and whoever prays while lying gets half the reward of that who prays while sitting.’ “
[Sahih Bukhari – Book 20 – Hadith 217]
