Our Lord! Indeed, You will gather all mankind on a Day about which there is no doubt; indeed, Lord Allah doesn't breach in His Promises.
Day of Judgment is the Day of Mutual Loss and Gain as told in verse 64: 9. The Day of Judgment is a Day in which everyone will get his/her Record fastened upon the neck as an Illuminated Open Book explained in verses 17: 13-14. Whoever made his Recording Book under the Light of Adhikr, will only triumph. Those who are unaware of this Recording Book and don’t become a believer with Adhikr, are the losers. Both verses 3: 194 and 13: 31 end as: “Indeed, Lord Allah will never breach the Promises”. Verse 13: 31 also ends as: “Indeed, Allah doesn't breach in His Promises”. Verse 3: 194 ends as: “Indeed, You never breach the promises”. See explanation 2: 254.
