Allah is the Light of the heavens and the earth. The similitude of His light is as a niche wherein is a lamp. The lamp is in a glass. The glass is as it were a shining star. (This lamp is) kindled from a blessed tree, an olive neither of the East nor of the West, whose oil would almost glow forth (of itself) though no fire touched it. Light upon light. Allah guideth unto His light whom He will. And Allah speaketh to mankind in allegories, for Allah is Knower of all things. 024:035
A man once asked Abû Hurayrah – Allâh be pleased with him, ‘What is al-taqwâ?” He replied, “Have you ever taken a path filled with thorns?” The man replied, “I have.” Abû Hurayrah asked him, “What did you do?” He replied, “When I saw a thorn I would dodge it or pass over it or behind it.” Abû Hurayrah said, “That is al-taqwâ.”
