Notice when someone around you always bad mouths one particular person or a group. Pray for them. Pray they get better because jealousy, obsession and envy are all diseases of the heart. Lastly gtf away from them.
I pray Allah removes everyone from your life who secretly gossips about you and wishes ill against you this Ramadan. I pray Allah replaces them with people who rejoice for and with you; genuine people who wants to see you win.
