Assalamwalekum,If you think that someone has put a bad eye on your business, at home, or in marriage and all the blessings have been reduced, then you should read Nazar ki Dua from Quran.
You will get the benefit of it very soon. Insha Allah as soon as you recite this dua many times, your every problem and every problem caused by bad eyes will be solved.
If anyone was attracted by Nazar then a person should recite this Dua 11 times and blow over that person, doing so will remove all the Nazar.
Before reciting this dua also do wazu and before and after reading this Nazar ki dua also read three times Darood Ibrahim.
InshaAllah, you will be protected by Allah almighty from all the bad evil and Nazar.
