I have read about the benefits of reciting Allah's names at various sites including duas.org and islamic path.org. I have read that reciting each name is associated with a special benefit. I would like to know whether all this information associated with the 99 names of Allah, is true or not ? Kindly reply me. Thankyou in advance.

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

After investigating and researching the books of the scholars that we have at hand, we have not come across any evidence that there is a special benefit of reciting every one of the Most Beautiful Names of Allaah. However, there is much good and a great reward in reciting Allaah’s Names as a Muslim should memorize them and act upon them. Indeed, it is confirmed that the Prophet said: “Indeed, Allaah has ninety-nine names, one hundred minus one; and whoever believes in their meanings and acts accordingly will enter Paradise.” [Al-Bukhari and Muslim] For more benefit, please refer to Fataawa 94453 and 86663. 

Allaah Knows best.
