ابْتَسَمَ الصَّبَاحُ.
The morning smiled.
Morning is not a person, yet it is represented as possessing a human smile. The human analogue is left unexpressed, while a characteristic human action is assigned to morning.
Classical analyses differ in the finer taxonomy of makniyyah and takhyīliyyah. The essential application here is recognising an unstated human analogue and the attribute that evokes it.
