There are three names of Allah subhaanahu wata’ala in "Bismillaahir Rahmaanir Raheem and the following explanation was given by a speaker in one of our local Masjids (Shaykh Ridhwaan I believe) which I found truly inspiring and would like to share (though I doubt if I will be able to give it justice).

He explained the Barakah in the name "Allaah" with which things are able to come into existence without any means. Then through the Barakah of Ar-Rahmaan it takes form and finally through the Barakah of Ar-Raheem, it is preserved/ safeguarded for us to take benefit from.

He then asked why we need to call anyone other than Allah subhaanahau wata’ala when He it is Who has power over all things? He then recited the name of “Allah!” followed by "Laa-ilaaha illallaah!" (it sounded truly beautiful!) He then explained:

If one is need of Rizq (provision) who does one call? Ar Razzaaq is the Provider so call to Him thus; recite a few time s the wird of,

"Laa-ilaaha illallaah!” (There is no other worthy of worship except Allah!)

and add,

Laa Razzaaqa illallaah!" (There is no one to Provide except Allah!)

Now take the example of a young a man seeking a marraige partner. So let him recite,

"Laa-ilaaha illallaah! Laa Rahmaana illallaah!"
He will find his marraige partner and thereafter by reciting,

"Laa-ilaaha illallaah! Laa Raheema illallaah!"
His marriage will be safeguarded and only then will he fully benefit from it in every way.

Afterward I began to think of the various glorious names of Allah subhaanahu wata’ala and I felt that by applying the above we truly do not need to call anyone other than Allaah!

"Laa-ilaaha illallaah! Laa Kareema illallaah!”

"Laa-ilaaha illallaah! Laa Wahhaaba illallaah!”

"Laa-ilaaha illallaah! Laa Mujeeba illallaah!”

"Laa-ilaaha illallaah! Laa Ghaffaara illallaah!
