Al-Qadeer is the one whose power is perfect and complete, who is able to do all things. By His power He brought everything into existence, by it He arranges all the affairs, by it He fashioned and perfected the creation, by it He brings to life and causes to die. The one who, when He wills a thing to be, merely says 'Be!' and it is. He gave a child to Maryam without a father, made the fire cool for Ibrahim, and split the sea for Musa — nothing is beyond His perfect power.
“Is not He who created the heavens and the earth able to create the likes of them? Yes indeed! He is al-Khallaaq, al-Aleem.”
[Ya Sin (36): 81]
“Does man think that We cannot assemble his bones? Yes indeed, We are Qadir to put together in perfect order the tips of his fingers.”
[al-Qiyamah (75): 3-4]
