Praying upon other than the Prophet and making it a slogan for certain individuals

The questioner:
So the one who recites the words of prayer and peace upon the Prophet (peace and blessings be upon him) for all people, like the one who says, "Our master, may Allah pray upon him and grant him peace,"

The Shaykh:
that is valid, except if it is made a slogan for certain individuals. If this is made a slogan for certain individuals, as the Shi'ah do regarding 'Ali and their specific imams, that is not valid. But if it is not made a slogan, there is no harm. The Prophet (peace and blessings be upon him) , and Allah the Exalted said, "And pray upon them," meaning supplicate for them, for your prayer will reach them. So if it is not made a slogan for specific people, there is no harm.

The questioner:
And there is nothing [wrong with it].

The Shaykh:
So for this reason, the author said, as you heard, "May Allah pray upon him and his family and his Companions, and upon one like 'Abd," meaning may Allah pray upon one like 'Abd.
