Hadith text

Narrated Ibn Mas`ud:that Allah's Prophet led them in the Zuhr prayer and he offered either more or less rak`at, and it was said to him, "O Allah's Messenger (ﷺ) ! Has the prayer been reduced, or have you forgotten?" He asked, "What is that?" They said, "You have prayed so many rak`at." So he performed with them two more prostrations and said, "These two prostrations are to be performed by the person who does not know whether he has prayed more or less (rak`at) in which case he should seek to follow what is right. And then complete the rest (of the prayer) and perform two extra prostrations

Ibn Masud bataate hain ke Allah ke Nabi (SAW) ne unhein Zuhr ki namaz padhaayi aur ya to zyaada ya kam rakat padhi, aur unse kaha gaya, 'Aye Allah ke Rasool! Kya namaz kam kar di gayi hai, ya aap bhool gaye?' Unhone pucha, 'Wo kya hai?' Unhone kaha, 'Aapne itni rakat padhi.' To unhone unke saath do aur sajde kiye aur kaha, 'Ye do sajde us shaks ko karne chaahiye jise pata na ho ke usne zyaada ya kam rakat padhi hai, jismein use sahi cheez ka pata lagaana chaahiye. Aur phir baaki (namaz) poori karni chaahiye aur do izaafi sajde karne chaahiye.'
