This text passage relates that Yûsuf asked his brothers about the condition of his father, and they informed him that his father's eyes had turned white (become blind) from the sorrow of losing Bünyamin, after which Yûsuf told them that he would be able to see again and asked them to bring his entire family to him.

قال لهم يوسف: ما فعل أبي بعدي؟ قالوا: لما فاته بنيامين عمي من الحزن، قال: يقول: يعد بصيرا يقول: وجيئوني بجميع أهلكم

According to this text, Jacob's eyes becoming sightless resulted from continuous weeping caused by continuous sorrow for Yusuf; continuous weeping left a cloudiness in the eye (darkening) leading to blindness. According to some views, Jacob was not completely blind but had only weak vision. Furthermore, narrations are reported such as Gabriel coming to Yusuf while he was in prison and informing him of his father's sorrow, the story of Yusuf's shirt being transported to Canaan, and the separation period between Jacob and Yusuf being eighty years.

قالوا : الحزن الدائم يوجب البكاء الدائم وهو يوجب العمى ، فالحزن كان سببا للعمى بهذه الواسطة ، وإنما كان البكاء الدائم يوجب العمى ، لأنه يورث كدورة في سوداء العين

According to Kurtubî, the shirt that Yûsuf sent to his father was not an ordinary garment; it was a sacred shirt made from paradise silk that Abraham wore in the fire, and it passed from Isaac to Jacob, and from him to Yûsuf. Gabriel informed Yûsuf that this shirt contained the scent of paradise and that this scent would heal without touching any sick person or one afflicted with calamity. The text also relates that it was Judah who carried the shirt and that previously he had brought a shirt stained with false blood that saddened his father, but now he was carrying it to make him happy.

ولكن ذلك قميص إبراهيم الذي ألبسه الله في النار من حرير الجنة وكان كساه إسحاق وكان إسحاق كساه يعقوب وكان يعقوب أدرج ذلك القميص في قصبة من فضة وعلقه في عنق لما كان يخاف عليه من العين وأخبره جبريل بأن أرسل قميصك فإن فيه ريح الجنة وإن ريح الجنة لا يقع على سقيم ولا مبتلى إلا عوفي

According to this exegete, Jacob's eyes became sightless from weeping greatly for Yusuf and his brother; the expression applies not only to one person but to a condition concerning all of Jacob's children.

وكان قد عمى من كثرة البكاء أي بجميع بني يعقوب

According to Beydâvî, the expression 'lâ tesrîbe aleyküm' indicates that it was not a rebuke directed by Yûsuf at his brothers; the word 'tesrîb' is used metaphorically from 'sarb', which means the peeling and cleaning of the fat surrounding the belly, to express harsh blame that causes someone to lose face and damages their dignity. The word 'el-yevm' is either connected to 'lâ tesrîbe' (today, even though it is the most likely day, I do not rebuke you, so how would I rebuke you on other days) or connected to the expression 'yağfirullahu leküm' because Yûsuf had forgiven their transgression at that moment and they had confessed their sin. Furthermore, a report is related regarding Yûsuf's miraculous quality: when his brothers recognized him, they said they felt ashamed before him, and he told them that the people of Egypt had previously looked upon him as a slave sold for twenty dirhams, but when he appeared with his brothers, he became honored in their eyes and it became known that he was from the lineage of Abraham.

لا تأنيب عليكم تفعيل من الثرب وهو الشحم الذي يغشى الكرش للإزالة كالتجليد، فاستعير للتقريع الذي يمزق العرض ويذهب ماء الوجه.

Zemahşerî indicates that the word 'basîran' is used in the sense of 'sâra' (became/was transformed), that is, his eye would become seeing. Furthermore, it is related that the one who carried the shirt to Jacob was Judah, and because he had previously grieved him with the blood-stained shirt, he now wished to make him happy with this shirt, and he carried the shirt barefoot from Egypt to Canaan, a distance of eighty parasangs on foot.
