Ar-Rahmaan - The Most Beneficent

This Name is describing the Lord with Mercy, Generosity, Kindness, and to the great expanse of His Mercy and Generosity that encompasses all that is existence being granted in accordance to what His Wisdom dictates. The believers have been specifically singled out for this and they are granted a goodly and the best portion of this as Allah said, "My mercy encompasses all things." So I will decree it (especially) for those who fear Me and give zakah and those who believe in Our verses." (Quran, 7:156)

So the blessings and the good are all from the effects of His Mercy, Generosity and Kindness just as all the goodness in this world and in the Hereafter is from the effects of His Mercy. "Indeed, we used to supplicate Him before. Indeed, it is He who is the Beneficent, the Merciful." (Quran, 52:28)

"Our Lord, let not our hearts deviate after You have guided us and grant us from Yourself mercy. Indeed, You are the Bestower." (Quran, 3:8)

"And And if it had not been for the favor of Allah upon you and His mercy... and because Allah is Kind and Merciful." (Quran, 24:20)

"O mankind, what has deceived you concerning your Lord, the Generous." (Quran, 82:6)
