Surat Al-Kahf (The Cave) - سورة الكهف

: And who does more wrong than he who is reminded of the Ayat (proofs, evidences, verses, lessons, signs, revelations, etc.) of his Lord, but turns away from them forgetting what (deeds) his hands have sent forth. Truly, We have set veils over their hearts lest they should understand this (the Quran), and in their ears, deafness. And if you (O Muhammad SAW) call them to guidance, even then they will never be guided.

: And your Lord is Most Forgiving, Owner of Mercy. Were He to call them to account for what they have earned, then surely, He would have hastened their punishment. But they have their appointed time, beyond which they will find no escape.

: And these towns (population, 'Ad, Thamud, etc.) We destroyed when they did wrong. And We appointed a fixed time for their destruction.

: And (remember) when Musa (Moses) said to his boy-servant: "I will not give up (travelling) until I reach the junction of the two seas or (until) I spend years and years in travelling."

: But when they reached the junction of the two seas, they forgot their fish, and it took its way through the sea as in a tunnel.

: So when they had passed further on (beyond that fixed place), Musa (Moses) said to his boy-servant: "Bring us our morning meal; truly, we have suffered much fatigue in this, our journey."

: He said:"Do you remember when we betook ourselves to the rock? I indeed forgot the fish, none but Shaitan (Satan) made me forget to remember it. It took its course into the sea in a strange (way)!"
