Allah tells us that He is the Owner of all things, and that everything is easy for Him. He has the supplies for all things with Him.
وَمَا نُنَزِّلُهُ إِلاَّ بِقَدَرٍ مَّعْلُومٍ
(and We do not send it down but in a known measure.) meaning, as He wills and as He wants. Doing so out of His great wisdom and mercy towards His servants, in a way that He is under no obligation to do. But He has decreed mercy for Himself. Yazid bin Abi Ziyad reported from Abu Juhayfah that `Abdullah said: "No year has more rain than another, but Allah divides the rain between them as He wills, it rains here a year and there a year. Then he recited:
Going Ahead and Remaining Behind in Righteous Deeds: The Difference in Degrees
Some exegetic interpretations of the words: (al-mustaqdimin) : 'those who go ahead' and: (al-musta'khirin) : 'those who remain behind' appearing in verse 24: الْمُسْتَقْدِمِينَ ~.A11 have been variously reported from Tafsir authorities among the Sahabah ؓ and Tabi` in. These are:
1. 'Al-Mustaqdimin' are those born to date, and 'Al-Musta'khirin' are those not born yet [ Qatadah and ` Ikrimah ].
2. 'Al-Mustaqdimin' means the dead, and 'Al-Musta'khirin' means those alive till now [ Ibn ` Abbas and Dahhak ]
3. 'Al-Mustaqdimin' signifies good people who came before the appearance of the Ummah of the Holy Prophet ﷺ ، and 'Al-Mustakhirin' refers to his Ummah itself [ Mujahid ].
The settling of human beings in the world and then their being taken away from here are events which occur at the behest of God. Had this been dependent on the will of man, he could never have come here and after coming here, he would never have gone on to the world of the Hereafter. This also proves that before the creation of human beings, heaven and earth belonged to God and thereafter they will also belong to God. There are innumerable things on earth, but everything has its own individuality. Everything performs the special role assigned to it. This proves that the Creator of the earth has knowledge of each and every thing. He has allocated a particular function to everything, so much so that the thumb impression of one man is different from that of any other man. For such a Powerful and Knowledgeable Being (that is, God) it is not difficult to keep every man’s reckoning separately and deal with him in exactly the way he deserves to be treated.
