Surah 12. Yusuf, Ayah 63

Lit., "measure [of grain]", here used metonymically in an allusion to Joseph's words (verse {60}).

On their return they no doubt told Jacob all that had transpired. But to beg Benjamin of him was no easy matter, as Jacob did not trust them and had no cause to trust them after their treatment of Joseph, So they use the argument of urgent necessity for all it is worth.
