What is the authenticity of the supplications (duas) circulated in forums for bringing about a husband's love and guidance, and what is the ruling on adhering to them and reciting them constantly if they are not authentic?

This supplication is not authentically reported (ma'thur), but there is no harm in supplicating with it due to the soundness of its phrases and its nature as a general supplication, provided that one does not believe it possesses a specific virtue or adhere to it as if it were authentically reported in the Sunnah. Nevertheless, it should not be widely circulated among people to avoid them thinking that it is from the Prophet's Sunnah.
