A person or thing may be referred to by a former state or by an anticipated future state. The relation is temporal, not similarity-based.
«وَآتُوا الْيَتَامَىٰ أَمْوَالَهُمْ»
Give orphans their property.
The order to hand over full control of property applies when recipients have attained the relevant maturity. The term “orphans” retains the earlier designation and emphasizes their rights. Referring to something by a later state works conversely; both are temporal non-similarity relations.
