The Ruling on Acting Upon Weak Hadiths and Fabricated Hadiths in Matters of Worship

Question:
Do we act upon weak hadiths and fabricated hadiths in matters of worship?

Answer:
As for fabricated hadiths, it is not permissible to mention them or cite them as evidence, except to warn of their falsehood and to caution against them.
As for weak hadiths, there is nothing wrong with mentioning them for encouraging good and warning against evil, but they should not be cited as evidence, and it is better and more preferable to dispense with them in favor of authentic hadiths.
