Tafsir of Ya seen 36:82

Yes, indeed! He is the All-Knowing Supreme Creator. Verily, His command, when He intends a thing, is only that He says to it, "Be!''-- and it is! meaning, He only needs to command a thing once; it does not need to be repeated or confirmed. When Allah wants a thing to happen, He only says to it: "Be!'' once, and it is. Imam Ahmad recorded that Abu Dharr, may Allah be pleased with him, said that the Messenger of Allah said:

إن الله تعالى يقول

يا عبادي كلكم مذنب إﻻ من عافيت فاستغفروني أغفر لكم وكلكم فقير إﻻ من أغنيت إني جواد ماجد واجد أفعل ما أشاء عطايي كﻼم وعذابي كﻼم إذا أردت شييا فٳنما أقول له كن فيكون

Allah, may He be exalted, says: "O My servants, all of you are sinners apart from those whom I protect from sin. Seek My forgiveness and I will forgive you. All of you are in need except for those whom I make independent. I am Most Generous, Majestic, and I do whatever I will. My giving is a word and My punishment is a word. When I want a thing to happen I merely say to it `Be!' and it is.''

فسبحان الذي بيده ملكوت كل شيء وإليه ترجعون
