Likewise, the king of Egypt saw the seven-year drought in the form of seven lean cows eating the seven fat cows and also, the seven green ears of corn and the seven dry ears. Similarly, the dreams of Joseph's two fellow-inmates in the prison: one saw himself pouring wine for the king (in the form of the first pressing of wine), while the second saw himself crucified (in the form of birds eating from the bread basket on his head).
The dream of the king of Egypt is related in the same chapter, verse 43 and its interpretation, from Joseph, in verses 47-49 when he says: you will sow seven years as usual, but what ever you reap leave it in the ear, all except a little which you will eat. Then after that will come a year when people will have plenteous crops and then they will press (meaning wine and oil). The dream of Joseph's fellow-inmates in the prison occurs in verse 36 of the same chapter.
One of the two young men says to Joseph: "I dreamt that I was carrying upon my head bread which the birds were eating. " The interpretation of the dream is related by Joseph in verse 41: "O my two fellow-prisoners! As for one of you he will pour out wine for his Lord to drink and as for the other, he will be crucified so that the birds will eat from his head. " In a similar fashion, God relates the story of Moses and Khidr in the chapter "The Cave" [XVIII:71-82].
Khidr made a hole in the boats; thereafter, killed a boy and, finally, straightened a leaning wall. After each event, Moses protested and Khidr explained the meaning and reality of each action which he had carried out on the orders of God; this he referred to as ta'wil. Thus it is clear that the reality of the event and the dream-picture which portrayed the event-to-be are basically the same: the ta'wil, or interpretation, does not have a meaning other than the apparent one.
Likewise God says, talking about weights and measures: Fill the measure when you measure and weigh with a right balance, that is proper and better in the end," (that is, more fitting in the final determination of the Day of Reckoning) [XVII:35]. It is clear that the word ta'wil used here in respect to the measuring and weighing refers to fair dealing in business practices.
Thus the ta'wil used in this way is not different from the literal meaning of the words "measuring" and "weighing"; it merely deepens and extends the significance of the mundane to include a spiritual dimension.
