Asalam alaykum 
I know it's a good thing to read the names of Allah. But I was wondering that I've read on the internet that if you recite any of Allah's names a certain times certain things happen.. for example one name you recite a lot it will make it easy for you on the day of judgement or another that you can recite for istikhara etc. Is this allowed? some say it's wrong? maybe it's proved success for people? idk :/ Thank you.
