السلام عليكم ورحمة الله وبركاته احسن الله اليك I saw a video of Imam al-Albani رحمه الله saying that adding "WaMaghfiratuh" in the salaam when you are replying (not the first to give it) is a valid thing. Is this something we should practice, and if there are different sayings which is most correct?

Different sayings i have not reached a conclusion so Allah knows best.
