Is it permissible for a Muslim to obligate himself to pray upon the Prophet (peace be upon him) one hundred times on Friday, in order to gain reward and manage time, without believing in any specific virtue for this number or obligating others to do so?
There is no harm in sending blessings upon the Prophet, peace and blessings be upon him, one hundred times on Friday, as long as one does not believe it to be a Sunnah specific to this particular time or consistently adhere to this exact number.
