A woman who was alot into this kind of 'wazifa' reading practices was having serious issues in her married life. Her inlaws against her and after their son to divorce her and marry another. She started reading practically everything that people would tell her to to 'improve' her situation. She blindly followed as she was desperate to save her marriage. At one point, she started to have psychological issues. She bumped into some witch who told her to follow some new dirty practice which was definitely NOT Islamic. She knew that but by then because all those 'wazifas' she was reading were providing the opposite results that she gave that new dirty thing a try. I do not know the details of what she did. All I know is that it was some 'dirty' cult and in no way Islamic.
Within days, she had her hubby all over her in every sense. Again, I do not have time to state the details here. That lasted a year or so. Within two years, things got so bad for her again that her lovey dovey hubby divorced her along with their 3 kids.
As any true Islamic scholar will always tell you. True islamic solution to ANY problem is nothing but keeping regular PRAYERS and DUAS. And as someone else suggested above, 'TAHAJJUD' prayer is the most precious of all the prayers and has too much sawab. I read somewhere that ANY dua made at 'Tahajjud' time is NEVER rejected. The only condition is that your dua should come out from your heart. No other solution can beat that. Wazifas to avoid at best and any kind of other cult practices has no significance in islam but that comes from hinduism.
Could you please share an incident/example, or two?
