That is from the news of the unseen which We reveal into you; neither you nor your people were knowing It before this, so you be patient, indeed the ultimate victory is for the heedful.
“Indeed, the ultimate victory is for the heedful” means that only those who follow the Messengers, Prophets, and believers in the Lord’s party will prosper in this world and the Hereafter, as explained in verses 5:54-56. Adhikr, the Best Interpretation of the Lord's Book, is now available as a Book. Those who use it as a safeguard against calamities, disasters, diseases, and Hell are considered heedful and will achieve the ultimate victory, as explained in verses 3:101 and 5:48. Verse 20:132 concludes: "The ultimate consequence is for the heedful." See explanation 2:185, 251-252; 3:44, and 10:102-103.
