21:10
لَقَدْ أَنزَلْنَآ إِلَيْكُمْ كِتَـٰبًا فِيهِ ذِكْرُكُمْ ۖ أَفَلَا تَعْقِلُونَ
laqad anzalnā ilaykum kitāban fīhi dhik'rukum afalā taʿqilūna
And now We have sent down to you [people] a Scripture to remind you. Will you not use your reason?
Indeed, We have sent down for you (O mankind) a Book (the Qur’ân) in which there is Dhikrukum,(your Reminder or an honour for you i.e. honour for the one who follows the teaching of the Qur’ân and acts on its teachings). Will you not then understand?
