A lesson from surah Kahf
The first story that is mentioned in the Surah is the story of the men of cave. They were the people who were believers and lived in a country of non-believers. Thus, when they noticed that people will threat their lives because of the faith, they leave the city and go to a cave for the sake of Allah and their faith. Thus, there Allah Almighty bestowed sleep over them and when they woke up from their sleep, by that time all the people of their city had become believers. Thus, this story shows that when a person puts his or her belief in Allah Almighty, He always comes to their rescue and helps them in easing their difficulties.
Lesson – The lesson to learn from this story is that Allah Almighty puts the faith of a person to trial. When Allah Almighty puts the faith to trial and when a believer is steadfast in his or her faith, then Allah assists them in ways that are beyond comprehension. Moreover, the story also gives the lesson that a Muslim must always remain in the company of people who are good and righteous. The men of cave were all righteous, thus, their being together is one of the factors that attracted the mercy and assistance of Allah Almighty. Thus, a Muslim should be steadfast in his or her faith and remain in the company of good people, as is mentioned in Quran:
🌟And keep yourself patient [by being] with those who call upon their Lord in the morning and the evening, seeking His countenance. And let not your eyes pass beyond them, desiring adornments of the worldly life, and do not obey one whose heart We have made heedless of Our remembrance and who follows his desire and whose affair is ever [in] neglect.🌟 (18:28)
