The word: صرح (sarh) in verse 36: وَقَالَ فِرْعَوْنُ يَا هَامَانُ ابْنِ لِي صَرْحًا (And the Pharaoh said, "0 Haman, make a tower for me,) means a structure that rises high. An outward look at this statement suggests that the Pharaoh ordered his minister, Haman to build a structure that rises high into the sky close enough for him to go up, peek in and have a glimpse of God. If this wild thought, not imaginable even in the case of a man of very ordinary commonsense, really comes from Pharaoh, the sole master of the kingdom of Egypt, then, it is an evidence of his unbelievable folly - and if the minister carried out his orders, then, the apple did not fall far from the tree, as the king, so the courtier! Since no one expects any head of the state to go that wild in his imagination, therefore, some commentators have said that this much he too knew that, no matter how high a structure is made for him, he still cannot reach the skies (by that mode of ascent). But, he did that only to impress or confuse his people. Then, we have no sound and strong report to prove whether or not such a palatial high structure was ever raised. However, al-Qurtubi reports that this building was constructed, but once it reached its higher levels, it collapsed.
My respected father, Maulana Muhammad Yasin, a dear disciple of Maulana Muhammad Ya` qub, the first principal of the famous Darul-` Uloom of Deoband in India has reported his learned teacher saying, 'For this lofty palace to collapse, it is not necessary that it be hit by some Divine punishment. The fact is that the height of every building depends on the capability of its foundation to bear weight. No matter how deep the foundation is laid, it cannot go deeper than a certain limit. Now, when levels after levels were added to this building, it was inevitable that, once it exceeded the capability of its foundation to bear additional weight, it must collapse.' This provides another proof of the folly of Pharaoh and Haman. Allah knows best.
