“Allah the exalted said, ‘ I am Ar Rahman. I created the Raham (womb) and derived a name for it from My name. Hence whoever keeps it, I will keep ties to him, and whosoever severs it, I will sever ties with him'” Tirmidhi recorded in Tafsir ibn Kathir
From this we can see the importance of calling Allah by this name on a regualr basis. Allah swt likened His name Ar-Rahman, and the importance of keeping it to the importance of family ties, by reminding us of the root of the word. Cutting ourselves off from this name can be seen as similar to cutting ourselves off from the ties of the womb.
SubhanAllah, when we say the words Ar Rahman, do we realise in our hearts that this is a means of keeping ties with Allah? that without us supplicating to this name Allah would distance himself from us?
Also another important point is we often talk about the root of words backwards. Allah is not called Ar- Rahman as He swt is similar to the mercy shown to us in the womb, but the womb is called Raham after Allah’s name! Allahs attributes and names are eternal and everlasting. They have always been.
“Then He rose over the throne in a manner that suits His majesty), Ar Rahman” 22.59
demonstrating that Allah’s Rahma is something that encompasses all of creation.
“Allah vreated one hundred mercies, then he put one of them among his creatures by which they love one another, and Allah has the other ninety nine” Al Bukhari SubhanAllah, we cannot come near to imagining the compassion Allah has for his creation, it is million times more then what a mother has for her child, as a mother has one part of the compassion that she shares with all other creatures in creation and Allah has kept 99 parts!
“Our Lord, we believe; therefore forgive us and have mercy on us, for you are the best of the merciful.” 23:109
