Ilayhi yuraddu AAilmu assaAAati wama takhruju min thamaratin min akmamiha wama tahmilu (surah Fussilat: 47)

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

(41:47) The knowledge of the Hour *61 rests solely with Him. *60 Not a fruit comes forth from its sheath, nor does any female conceive nor give birth to a child but it is in His knowledge. *62 On that Day He will call out to them: 'Where are those associates of Mine?' They will answer: 'We have declared to You that none of us can bear witness to that.' *63

Ilaihi yuraddu `ilmus Saaa`ah; wa maa takhruju min samaraatim min akmaamihaa wa maa tahmilu min unsaa wa laa tada`u illaa bi`ilmih; wa Yawma yunaadeehim aina shurakaaa`ee qaalooo aazannaaka maa minnaa min shaheed

*60) That is, "None but Allah knows when the Hour would occur. " This is the answer to the disbelievers' question as to when the threat being given them of meeting with the consequences of their evil deeds will be carried out. Allah has answered their question without citing it.
*61) "The Hour": the Hour of Resurrection, i.e. the Hour when the evildoers will be punished for their evil and the grievances of the oppressed good people will be redressed.
*62) By this the listeners have been made to realize two things: (1) That not only of Resurrection but the knowledge of all unseen things is reserved for Allah alone; there is no other knower of the unseen; and (2) that God Who possesses the detailed knowledge of the most minor things cannot remain unaware of the acts and deeds of anybody. Therefore, no one in His Kingdom should act fearlessly, with impunity. Only according to this second meaning the sentence becomes relevant to what follows. If one studies the following sentences the theme that immediately becomes obvious is: "Don't concern your selves about finding our the date of the coming of Resurrection; you should, however, be anxious about the consequences of your deviations you will have to bear when it comes. "This same thing had the Holy Prophet once said to a person, who asked him the date of the coming of Resurrection. All the major collections of Hadith contain a commonly reported Tradition to the effect: "Once when the Holy Prophet was on a journey, a man on the way shouted his name from a distance. The Holy Prophet asked what he wanted to say. He said: When will Resurrection come? The Holy Prophet replied: It must come in any case! What preparations have you made for it?"
*63) That is, "Now we have realized that what we had in our minds was absolutely wrong. Now none among us is of the view that there is another one also who is Your associate in Godhead." The words "we have submitted" show that on the Day of Resurrection the disbelievers will be asked again and again, on every occasion, "In the world you went on refusing to believe what the Messengers of God said: now say who was in the right: they or you? And the disbelievers will every time confess that the truth indeed was that which the Messengers preached and they themselves were in the wrong because they forsook the knowledge and persisted in their own ignorance.
