Assalam u Alaikum. Recently somebody gave a paste of various things they call 'lubhan' to one of my relatives. The giver told them that it is mentioned in Quran and it is burned around the holy Kaabah as well. They say that she should give the Dhuni (burning) of Lubhan in your house now and then to ward of evil possessions and shayateen and bring barkah. Please explain in the light of quran o sunnah the correct method. Jazak Allah
