Allah (swt) has 99 beautiful names and Insha'allah I shall post all the 99 Names Of Allah (swt) on my blog along with its virtues and meaning.
As with all Dua's one very important thing to remember is that for any Dua's to work you have to have full faith in Allah (SWT).
When adopting a particular name as Wazeefa (daily recital) add (Yaa) before the name and remove the (Al).
For example, (Ar-Rahmaan) must be recited as (Yaa-Rahmaanu) and NOT as (Yaa-Ar-Rahmaanu).
1. Allah (The Name of Allah)
2. AR-RAHMAN (The Most Gracious)
3. Ar-Raheem: (The Most Merciful)
If you recite this name of Allah 100 times daily after every Salaah (prayer), Allah will safeguard you against all calamities and maladies. Insha-Allah.
