Man kana yarjoo liqaa Allahi fa-inna ajala Allahi laatin wahuwa assameeAAu alAAaleem (surah Ankabut: 5)

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

(29:5) Let him who looks forward to meeting Allah know that Allah's appointed term will surely come to pass. *6 He is All-Hearing, All-Knowing. *7

Man kaana yarjoo liqaaa `allaahi fa inna ajalal laahi laaat; wa Huwass Sameeul `Aleem

*6) That is, "The case of the one who does not believe in the life hereafter and thinks he is answerable to none for his deeds and there is no accountability whatever, is different. He may remain heedless and act as he likes, for he will himself see the consequences when they appear against his expectations. But those who expect that they have to meet their Lord one day and rewarded and punished according to their. deeds, should not have the misunderstanding that the time of death is yet tar off. They should rather think that it is near at hand and the respite for action is about to come to an end. Therefore, whatever they can do for their well-being in the Hereafter, they should do. They should not delay self-reform on account of the baseless belief that they have yet to live a long life."
*7) That is, "That God before Whom they will appear to render their accounts is not uninformed. He hears everything and knows every thing, and nothing about them is hidden from Him."
