ANSWER:

The Prophet salla  Allahu alaihi wa sallam was a human being and acts like one.

He doesn’t make errors in delivering the message and the rulings as this is a revelation from Allah. But he may fall sick and he may feel the pain and forget.

 

If Prophet Muhammad (SAW) is free from forgetfulness, then why did Prophet(SAW) did the Sujood of Forgetfulness if he did not forget how much raka’ah he has prayed?
