السلام عليكم ورحمة الله وبركاته In L23 of Manhaj As-Salikeen it mentions that the minimum requirement for الصلاة الإبراهيمية is اللهم صل على محمد أو اللهم صل على النبي or other correct ways of saying. Is this allowed only for those who did not memorise it or are unable to say it or for everyone?

Everyone as we mentioned in class
