It should be remembered that it is compulsory to write or recite Durood when writing the name of Rasulullaah صلى الله عليه وسلم,
or when saying his name. This is greatly emphasized in the Hadith and there are grave warnings for the person who goes against this teaching. Also, it is necessary to write the entire Durood after the name of Rasulullaah صلى الله عليه وسلم. The command of Durood will not be fulfilled by writing (saw) or any other shortened form, nor will a person get reward.
