English Translation
It was narrated from 'Abdullah ibn Mas'ud (رضي الله عنه) — via Muhammad ibn Fudayl, from Khusayf, from Abi 'Ubayda ibn 'Abdillah — that 'Abdullah ibn Mas'ud said: 'If you doubt during your prayer while sitting — not knowing whether you prayed three or four [rak'as]: if your stronger opinion is that you prayed three, then stand and bow one more rak'a, then give the salam, then perform two prostrations, then do the tashahhud, then give the salam. And if your stronger opinion is that you prayed four, then give the salam, then perform two prostrations, then do the tashahhud, then give the salam.'
