What is the ruling on the Tashahhud and the two Taslims after the prostration of forgetfulness if it is performed after the Salām?

The two taslims after the prostration of forgetfulness (sujud al-sahw) that occurs after the salutation (taslim) are obligatory. As for the tashahhud, it is recommended according to Imam Ahmad if the prostration of forgetfulness is after the salutation. If one prostrates and then salutes without reciting the tashahhud, there is no blame upon him.
