Surah As-Saffah (Those Angels Lines up in Ranks), Verse 102

فَلَمَّا بَلَغَ مَعَهُ السَّعْیَ قَالَ یٰبُنَیَّ اِنِّیْۤ اَرٰی فِی الْمَنَامِ اَنِّیْۤ اَذْبَحُكَ فَانْظُرْ مَاذَا تَرٰی قَالَ یٰۤاَبَتِ افْعَلْ مَا تُؤْمَرُ سَتَجِدُنِیْۤ اِنْ شَآءَ اللّٰهُ مِنَ الصّٰبِرِیْنَ ۟

Falamma balagha ma'a hus sa'ya qaala yaa buniya inneee araa fil manaami anneee azbahuka fanzur maazaa taraa; qaala yaaa abatif 'al maa tu'maru satajidunee in shaaa'allaahu minas saabireen

“Then, when (the son) reached (the age of) (serious) work with him, he said: "O my son! I see in vision that I offer thee in sacrifice: Now see what is thy view!" (The son) said: "O my father! Do as thou art commanded: thou will find me, if Allah so wills one practising Patience and Constancy!"”
