Surat Al-'Isrā' - سورة الإسراء

وَلَا تَقْرَبُوا مَالَ الْيَتِيمِ إِلَّا بِالَّتِي هِيَ أَحْسَنُ حَتَّىٰ يَبْلُغَ أَشُدَّهُ ۚ وَأَوْفُوا بِالْعَهْدِ ۖ إِنَّ الْعَهْدَ كَانَ مَسْئُولًا

Muhsin Khan: And come not near to the orphan's property except to improve it, until he attains the age of full strength. And fulfil (every) covenant. Verily! the covenant, will be questioned about.
