Whoever reflects upon Surat Al-Kahf will know that its meanings carry what would be incredibly beneficial for them in protecting them from the trials of this world and security from the dajjal. That is why its recitation was legislated every Friday out of Allah’s wisdom and mercy.
Surat Al-Kahf encompasses four stories, four different types of trials (fitan) and four causes of salvation:
1) The companions of the cave: The fitnah of religion.
Their story was of believing youth who were living amongst disbelievers and committed to migrate and flee with their religion after a clash between them and their people. Allah sufficed them with the mercy of the cave. When they awoke they found their entire community had become believers.
Their salvation: Righteous companionship.
2) The owner of the two gardens: The fitnah of wealth and children
The story of a man whom Allah blessed but forgot that blessing and belittled it. He was arrogant and didnt thank Allah for the blessings though his companion reminded him. When his wealth was destroyed he was remorseful when remorse didn’t count!
Salvation from that trial: Knowing the reality of the dunya
3) Musa and Khidr: The fitnah of knowledge.
The story of Musa when he was asked about who the most knowledgable person on earth was and he responded saying “me,” without referring that knowledge back to Allah, and so Allah revealed to him that indeed there was. Musa then traveled to learn from that person that the Divine Wisdom could be incomprehensible at times, but the One designing it is All-Wise. Like the harming of the ship for example.
Salvation from that trial: Humility
4) The story of Dhul Qarnain: The fitnah of power
The story of a great ruler who was given both knowledge and power and traveled the earth relieving hardship and spreading goodness. He solved the problem of Yajuj and Majuj by sealing them in the earth and in doing so was able to mobilize the resources of a people who could hardly understand his speech!
Salvation from that trial: Sincerity
