Translation: Our Lord! Grant us what Thou didst promise unto us through Thine apostles, and save us from shame on the Day of Judgment: For Thou never breakest Thy promise [3:194]

Tafseer: Such people do not doubt the fact that God will fulfil His promises. What they do doubt is whether they will be reckoned among those for whom those promises were made. Hence they pray to God to make them worthy of His promised rewards. They are afraid lest they remain targets of slander and ridicule by the unbelievers in this world, and then be disgraced in the Hereafter before the same unbelievers who may mock them once again saying that their faith has been of no avail to them.
