Surah Yusuf — Ayah 72 (12:72)
قَالُواْ نَفۡقِدُ صُوَاعَ ٱلۡمَلِكِ وَلِمَن جَآءَ بِهِۦ حِمۡلُ بَعِيرٖ وَأَنَا۠ بِهِۦ زَعِيمٞ ٧٢
English translation (Saheeh International)
They said, "We are missing the measure of the king. And for he who produces it is [the reward of] a camel's load, and I am responsible for it."
Brief commentary
The caller and his companions, who were with him, said to the brothers of Joseph that they were missing the bowl of the king which they measured with. Whoever produced the bowl of the king before the inspection would get a reward, which would be a camel load, and the speaker guaranteed this to whoever did so.
