﴿31﴾ قَالَ فَمَا خَطْبُكُمْ أيُّهَا الْمُرْسَلُونَ
that of Prophet Lot (AS), the former was informed by God Almighty through His angels that He intended to cause the destruction of the people of Lot (AS) inhabiting Mu'tafaka turning a deaf ear to Lot’s warnings against their committing such obscene acts. Thus they brought Divine torment upon themselves. Replying to Prophet Abraham (AS), the angels informed him that they had been sent by God Almighty to send down upon them stones of baked clay.
The blessed Verse 34 is saying: “O Muhammad (SAW)! Those stones marked by your Lord are for those people leading their lives in pleasures of the flesh, disbelief, and sin. The blessed Verse may make a reference to the point that the recompense of any act is to be consistent with it (jazā'an wifāqan). Since the promiscuous deeds of the people of Mu'tafaka were the lowliest acts against the laws of nature and human practice, but quite bestial, their chastisement had to be inflicted upon them by means of the lowliest of things, namely baked clay. It may be for the same reason that the punishment for sodomy is being stoned so that the sodomizer tastes the most excruciating torment in this world and others may take a lesson and refrain from committing such act of obscenity.
