Concise Quran Commentary
Now that you have moved away from your people, and have left what they worship instead of Allah, and you have worshipped Allah alone, then take refuge in the cave fleeing to protect your religion. Allah, may He be glorified, will shower His mercy on you to protect you from your enemies, and will make for you an easy means of livelihood that you could benefit from in place of the life that you had when living amongst your people.
