Why was the word "dream" (al-manam) mentioned in the vision of Ibrahim (peace be upon him) but not in the visions of Surat Yusuf?

The style of all the verses clarifies that what is meant by "vision" (ru'yah) is dream visions. This is indicated by the king's and the two young men's request for their interpretation, and Yusuf's later statement: "This is the interpretation of my vision." As for the vision of Abraham, peace be upon him, it occurred in a dream, which indicates the method of revelation through which the command came to him, for the visions of prophets are revelation.
