Yusuf pbuh told his brothers to take his shirt and put it over Yaqoub’s face, and he will get his sight back. And in fact, when the messenger got back with the shirt and put it over Yaqoub’s face, he got back his eye-sight.
(Go with this shirt of mine and cast it over my father’s face, and he will regain his sight. Then come back to me with your whole family.”) Yusuf 12:93
(But when the bearer of the good news arrived, he cast the shirt over Yaqoub’s face, so he regained his sight. Yaqoub then said ˹to his children˺, “Did I not tell you that I truly know from Allah what you do not know?”)Yusuf 12:96
يوسف عليه السلام أعطى قميصه لإخوته و قال لهم أن يضعوا القميص على وجه أبيهم. و سيعود نظره .و هو بالواقع لما دخلوا أبيهم و وضعوا القميص على وجهه عاد نظر يعقوب عليه السلام بصره.
( اذْهَبُوا بِقَمِيصِي هَـٰذَا فَأَلْقُوهُ عَلَىٰ وَجْهِ أَبِي يَأْتِ بَصِيرًا وَأْتُونِي بِأَهْلِكُمْ أَجْمَعِينَ ﴿٩٣﴾ وَلَمَّا فَصَلَتِ الْعِيرُ قَالَ أَبُوهُمْ إِنِّي لَأَجِدُ رِيحَ يُوسُفَ ۖ لَوْلَا أَن تُفَنِّدُونِ ﴿٩٤﴾ قَالُوا تَاللَّـهِ إِنَّكَ لَفِي ضَلَالِكَ الْقَدِيمِ
يوسف 12: 93
(فَلَمَّا أَن جَاءَ الْبَشِيرُ أَلْقَاهُ عَلَىٰ وَجْهِهِ فَارْتَدَّ بَصِيرًا ۖ قَالَ أَلَمْ أَقُل لَّكُمْ إِنِّي أَعْلَمُ مِنَ اللَّـهِ مَا لَا تَعْلَمُونَ
يوسف 12: 96
