Is it valid to be content with a single salutation to the right after the two prostrations of forgetfulness, after the Imam has given the two salutations of the prayer?

Whoever makes a single salutation after the two prostrations of forgetfulness (Sajdat al-Sahw) has done enough, and their action is valid. This is because it is reported that the Prophet, peace and blessings be upon him, performed the two prostrations of forgetfulness and then made the salutation, without specifying a particular number.
