Guardian of Faith, The One who witnessed for Himself that no one is God but Him "Sourat Al-Imraan: {18} There is no god but He: That is the witness of Allah, His angels, and those endued with knowledge, standing firm on justice. There is no god but He, the Exalted in Power, the Wise.". And He witnessed for His believers that they are truthful in their belief that no one is God but Him. This name also points to the fact that Allah pushes away off the believers anything that frightens, harms, or stresses them, and He grants them peace of mind and tranquillity instead. Some muslim scholars have explained this name as meaning the Creator and Giver of Peace, for He would not punish the believers in the hereafter. Subhan-Allah.

{41} O you who believe! Remember Allah with much remembrance. {42} And glorify His Praises morning and afternoon. {43} He it is Who sends Salat (His blessings) on you, and His angels too, that He may bring you out from darkness into light. And He is the ever Most Merciful to the believers.
