How should we perform Sujud-ul-Sahw (Prostration of Forgetfulness)?
Sujud-ul-Sahw consists of two prostrations performed after reciting the Last Tashahhud (testification recited in the sitting position in the last unit of Prayer). They are the same as the Sujud (prostration) performed in Salah (Prayer), and the Du`a' (supplication) and Adhkar (invocations and remembrances said at certain times on a regular basis) that are recited in them are the same. However, if Sujud-ul-Sahw is performed due to missing one or more Rak`ahs (units of Prayer), it is better to perform it after Taslim (salutation of peace ending the Prayer). Similarly, if the praying person who experiences Sahw (forgetfulness) completes the Salah based upon the number of (extra or missing) Rak`ahs they are more certain of, it is better to perform Sujud-ul-Sahw after saying Taslim, as there are many Sahih Hadiths (authentic Hadiths) indicating this.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
