Sayyiduna Ibn Abbas (may Allah be pleased with them both) said that the Noble Prophet (peace and blessings of Allah be upon him) forbade the sale of grain over which possession had not yet been taken. Sayyiduna Ibn Abbas said: I consider all things to be under the same ruling. (That is, whatever thing is purchased, it should not be sold before taking possession of it.)
