The isolation of the youth from surah Kahf
The isolation of the youth from surah Kahf from an astray, oppressing nation
Imâm Ibn Kathîr
” We narrate unto you their story with truth: Truly, they were young men who believed in their Lord (Allah), and We increased them in guidance. And We made their hearts firm and strong when they stood up and said: “Our Lord is the Lord of the heavens and the earth, never shall we call upon any god other than Him; if we did, we should indeed have uttered an enormity in disbelief. These our people have taken for worship gods other than Him. Why do they not bring for them a clear authority And who does more wrong than he who invents a lie against Allah. The young men said to one another:) “And when you withdraw from them, and that which they worship, except Allah, then seek refuge in the cave; your Lord will open a way for you from His mercy and will make easy for you your affair.” [Surah Kahf 17:13-16]
From here Allah begins to explain the story in detail. He states that they were boys or young men, and that they were more accepting of the truth and more guided than the elders who had become stubbornly set in their ways and clung to the religion of falsehood. For the same reason, most of those who responded to Allah and His Messenger were young people. As for the elders of Quraysh, most of them kept to their religion and only a few of them became Muslims. So Allah tells us that the people of the cave were young men. Mujahid said,
“I was informed that some of them wore some kind of earrings, then Allah guided them and inspired them to fear Him, so they recognized His Oneness, and bore witness that there is no god besides Him.”
“and We increased them in guidance.”
From this and other similar Ayat, several scholars, such as Al-Bukhari and others, understood that faith may increase, that it may vary in degrees, and that it may fluctuate. Allah says:
“and We increased them in guidance.”
