Q 4:
What should be said in Sujud-ul-Sahw (Prostration of Forgetfulness) and Sujud-ul-Tilawah (Prostration of Recitation)?
A:
In Sujud-ul-Sahw and Sujud-ul-Tilawah, you should say what you usually say in the Sujud (prostration) of regular Salah (prayer). This includes Tasbih (glorification of Allah) and Du`a' (supplication). These two Sujud (Sujud-ul-Sahw and Sujud-ul-Tilawah) are legislated by the Shari`ah (Islamic law), so they resemble the Sujud in regular Salah.
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
