﴿ فَلَمَّا بَلَغَ مَعَهُ ٱلسَّعْىَ قَالَ يَٰبُنَىَّ إِنِّىٓ أَرَىٰ فِى ٱلْمَنَامِ أَنِّىٓ أَذْبَحُكَ فَٱنظُرْ مَاذَا تَرَىٰ ۚ قَالَ يَٰٓأَبَتِ ٱفْعَلْ مَا تُؤْمَرُ ۖ سَتَجِدُنِىٓ إِن شَآءَ ٱللَّهُ مِنَ ٱلصَّٰبِرِينَ ﴾

“And [one day,] when [the child] had become old enough to share in his [father’s] endeavours, the latter said: “O my dear son! I have seen in a dream that I should sacrifice thee: consider, then, what would be thy view!” [Ishmael] answered: “O my father! Do as thou art bidden: thou wilt find me, if God so wills, among those who are patient in adversity!””
