مَنْ مَلَكَ ذَا رَحِمٍ مَحْرَمٍ مِنْهُ عَتَقَ عَلَيْهِ
Whoever acquires ownership of a close, permanently unmarriageable relative thereby emancipates that relative.
The acquisition of ownership is introduced as a condition, while emancipation is the legal consequence. The passage is particularly explicit about the consequence; ownership is mentioned as its condition.
This example shows that the presence of a word in a statement does not settle which legal point is naṣṣ. The text’s principal purpose and the relation of condition to consequence must be distinguished.
