the highest rank of faith, for it is a faith unmarred by doubt or hesitation: you are as certain of what is unseen as you are of what lies plainly before your eyes. When a person possesses complete certainty regarding all that Allah, exalted is He, has disclosed about the unseen—whether concerning Allah Himself, His names and attributes, the Last Day, or anything else—so that what Allah has reported becomes to him as palpable as something witnessed, that is the perfection of certitude.
His words, “that will make the calamities of this world easy for us to bear,” point to the fact that this worldly life is replete with trials. Yet when someone is convinced that such trials erase his sins and raise his rank—provided he remains patient and seeks his reward from Allah—the calamities become light and the ordeals, however great, are rendered manageable, whether they touch his body, his family, or his wealth. As long as complete certainty resides in his heart, afflictions are made easy for him.
“And allow us to enjoy our hearing, our sight, and our strength as long as You keep us alive.” Here he is asking Allah to let him benefit from these faculties—hearing, sight, and physical strength—for the duration of his life. When a person is granted the full use of these senses, he attains abundant good; when he is deprived of them, much good escapes him. Nevertheless, he is not blameworthy if their loss lies beyond his power.
“And make them the inheritor of us,” meaning: let our enjoyment of hearing, sight, and strength remain with us until the very end of our lives, so that they outlast everything else and accompany us to our final breath.
