The Meaning of the Saying of Allah the Exalted: "When the most wretched of them set out" and the Discussion of the Sign of Allah, the She-Camel

The Shaykh : That is, the most wretched of this tribe. And "ashqa" here, is it a verb or what? "Ashqa" means the most wretched of the people. So is it a verb or a non-verbal form? Please.
The student: A non-verbal form.

The Shaykh : This is a superlative noun. Well done, may Allah reward you. "Ashqa" means the most wretched of the people. It is a superlative noun, not a verb. "Inba'atha" means that when he was asked to slaughter the she-camel, he slaughtered it. He was their devil and their leader, as He the Mighty and Majestic said: What? . This she-camel was a sign among the signs of Allah; Allah Blessed and Exalted is He gave Salih this so that it would be clear that he was truly a messenger of Allah. The she-camel had its day of drinking, and they had their day of drinking, on a known day. It would come to this well, the Well of the She-Camel, which is known by this name today, and drink from it for a full day. On the second day, they would drink from this well. Some scholars said: On the day it comes and drinks, a person would bring it a bucket of water and take in exchange a bucket of milk. This was one of the signs of Allah; Allah the Exalted gave them this sign. But they disbelieved in it and slaughtered it. Their prophet said to them: . So they were warned of the punishment with a warning of a certain event. So they remained for three days, and the earthquake and the shout took them until they perished, the last of them.
