Waanna assaAAata atiyatun la rayba feeha waanna Allaha yabAAathu man fee alquboor (surah Hajj: 7)

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(22:7) and (this is a proof that) the Hour of Resurrection is sure to come and there is absolutely no doubt about it, and most surely He will raise up those who are lying in the graves. *9

Wa annas Saa`ata aatiya tul laa raiba feeha wa annal laaha yab`asuman fil quboor

*9) In this passage, different stages of the life of man, the effects of rain on the earth and the growth of vegetation have been cited as pointers to five realities:
(1) "Allah alone is the Truth".
(2) "He brings the dead to life".
(3) "He has power over everything".
(4) "The Day of Resurrection and the end of the world is inevitable".
(5) Most surely Allah will bring back to life all the people who have died", Let us now consider how these signs point to the above five realities:
(1) "Allah is the Truth": In order to prove this, let us first take the case of man. All the stages of his development are a clear proof that Allah has designed them with wisdom. He takes his birth from a sperm-drop which itself is produced in a wonderful manner. The food, which a man takes, turns into hair, flesh, bones and a part of it is turned into semen, which is potentially capable of producing millions of human beings. It is the Wise and True God Who decides which of these millions of seeds from the semen should be utilized to make a woman pregnant by mixing the seed with the egg-cell. This insignificant thing turns into a living child in nine months in the womb of the mother. If we consider the different stages of the child's birth we come to the inevitable conclusion that all these have been designed by the True, EverLiving Designer. For it is He Who decides whether it should be a male or a female, seeing or blind, etc. Then it is He Who decides how long a child is destined to live. All these things are a clear proof that Allah alone is the Truth.
(2) "He brings the dead to life": Even a little thinking on the right lines will convince every sensible and honest man that this process of bringing the dead to life is continuously going on before our eyes. Every human being has been created from a "dead" sperm-drop. Then he gets life from "dead things" like food containing dead matter like coal, iron, lime, salts, gases, which help make him a living human being. Then let us consider our surroundings. Seeds of different things which had been scattered here and there by the wind nad birds, and the roots of different kinds of vegetation which lay rotten and dead in the soil, spring up to life as soon as there occurs a sprinkling of rain water. This process of the dead coming to life is observed during every rainy season year after year.
(3) "Allah has power over everything": There are people who believe that no doubt Allah created everything and is governing the universe, but He cannot do anything in the future in addition to or apart from this. This is because they do not observe the phenomena of His powers which have been and are appearing every moment. They do not realize that if man-His creation ran perform wonderful feats of science which could not even be dreamt of in the former ages, why should Allah alone be held as having only limited powers ?
(4) "The Day of Resurrection is inevitable" and "Most surely Allah will bring back to life all the people who have died": These two are the rational corollaries of the preceding three premises. Allah is All-Powerful and therefore can bring about Resurrection at any moment He wills. He can also bring back to life all the dead people just as He brought to life human beings out of nothing in the first instance. As He is All-Wise, He has not created human beings without any object and purpose. He will judge their worldly lives in accordance with the object and purpose for which He created them. He will call them to account for everything He entrusted to them. This is very simple: even human beings ask one another to render an account of the property etc. they entrust to others. Likewise, Allah's wisdom requires to call every human being to account for the things entrusted to him. Then human nature also demands that there should be a differentiation between good and bad, and it expects the reward of good works and dreads the punishment of bad deeds. That is why the people have set up judicial courts. Thus man cannot imagine that the Creator will not call him to account for the things, powers and faculties, etc. which He has entrusted to him. Therefore common sense confirms that Allah will hold the Last Judgment so that every one should get his due reward and his due punishment.
