Tafsir of Ghafir 40:36

"And Pharaoh said, 'O Haman, construct for me a tower'" — a high, exposed structure, derived from the word sarh (tower), used when something is made manifest — "'that I might reach the ways'" — meaning the paths, as narrated from al-Suddi. Qatadah said: the gates. It is the plural of sabab (cause/means), and it is applied to everything by which one reaches a thing.
