The wisdom behind Lot (peace be upon him) beginning his call with the oneness of Allah

Question:
May Allah reward you. The Honorable Shaykh says: It has come in the Qur'an regarding the call of the messengers (peace be upon them) to their peoples. The first thing these messengers began with was calling their people to worship Allah (Mighty and Majestic). Allah (Mighty and Majestic) said regarding them: As for Lot (peace be upon him), it is not mentioned in his call that he began his people with the call to the oneness of Allah and His worship. The question is: What is the wisdom in that?

Answer:
Allah knows best. Perhaps the people were being called away from this heinous crime, so he called them to [abandon it], and they came to him saying, "Who among the people is more wicked?" They considered this crime to be the greatest of all. Whoever deems this crime permissible is a disbeliever. Whoever deems it permissible through preaching or through committing it is a disbeliever in Allah (Mighty and Majestic). As for the one who commits it but does not deem it permissible, he has committed a major sin, and the hadd punishment is carried out against him. If he is a virgin, he is stoned to death; if he is married, he is stoned until he dies. As for the one who commits sodomy, the scholars have stated that he is to be killed in all cases. The one who commits sodomy is killed in all cases, whether he is a virgin or married. The Prophet (peace and blessings be upon him) said, "The one who does it and the one it is done to." The Companions unanimously agreed on killing the one who commits sodomy, but they differed on the method of killing him. Some said he is to be burned with fire, as some of the Companions burned some of the sodomites. Some said he is to be thrown from the highest point in the city, as Allah did with the people of Lot, and they were pelted with stones. Some said he is to be killed by stoning until he dies. They agreed on the fact of his being killed, but they differed on the manner in which he is killed. This confirms the ruling regarding Lot. As for the fact that it did not come in Lot’s (peace be upon him) call that he said, "I do not [condone] this," this indicates that these people deemed this crime permissible and made it lawful. This is a deviation in their disbelief, may Allah protect us from it. Yes.
