The Quran Verse
Surah 12:93, 96
"[Joseph said], 'Take this shirt of mine and cast it over my father's face; he will become seeing...' And when the bearer of good tidings arrived, he cast it over his face, and he returned to sight."
The Bible (Genesis 45–46) never mentions Jacob going blind from grief, nor does it mention a magical shirt restoring his sight.
This is an example of magical realism being injected into a historical narrative. Jacob is transformed into a tragic, blind figure, and the shirt becomes a holy relic. This aligns more with the hagiography of later saints than with the grounded, realistic narratives of the Patriarchs in the Torah.
