Is it permissible to mention "O Allah, bless Muhammad and the family of Muhammad, as You blessed Abraham and the family of Abraham. O Allah, grant well-being to Muhammad and the family of Muhammad, as You granted well-being to Abraham and the family of Abraham in all the worlds, for You are Praiseworthy and Glorious," while generalizing that it earns a million good deeds, and then asking it to be sent to 10 people within an hour to earn 10 million good deeds?

Praying upon the Prophet, peace and blessings be upon him, carries great good and abundant reward. Whoever prays upon him once, Allah will pray upon him ten times. As for sending prayers upon the Prophet through social media to gain reward, there is no legitimate evidence to prove this. However, sending remembrances (adhkar), supplications (du'a), and beneficial information through social media with the intention of teaching people and reminding them carries great reward and much good. This is due to its role in disseminating knowledge and reminding others of good, and it falls under the general category of performing good deeds and reminding people.
