And also corn, with (its) `Asf, and Rayhan.
Ali bin Abi Talhah said that Ibn Abbas said that in,
وَالْحَبُّ ذُو الْعَصْفِ
(And also corn, with (its) `Asf), `Asf means straw."
Al-Awfi reported from Ibn Abbas,
"`Asf is green leaves cut from the stem, so it is called `Asf when it dries out."
Similarly, Qatadah, Ad-Dahhak and Abu Malik said that `Asfmeans straw.
Ibn Abbas, Mujahid and others said that Rayhan means leaves, while Al-Hasan said that it means sweet-scented plants.
Ali bin Abi Talhah reported that Ibn Abbas said that Rayhan means green leaves.
The meanings here, and Allah knows best, are the various crops that produce straw, such as wheat and barley, and Rayhan are the leaves that grow on the stems.
