وَقَالَ ذَرُوهُ إِنَّمَا نَفْعُهَا لَهُ
وَإِلَّا تَكُفُّوا قَاصِيَ الْبِرْكِ يَزْدَدِ
Meaning: An elder says: Leave him alone; the benefit of this she-camel is his. If you do not desist, the animals farther out in the herd will be added to the loss.
Dharūhu is an imperative addressed to a group: “leave him.” Innamā restricts or emphasizes the intended benefit, while wa-illā takuffū sets a condition: if you do not stop. The elder's intervention aims to prevent the camel incident from spreading into further harm.
