إِنَّمَا تُنذِرُ مَنِ اتَّبَعَ الذِّكْرَ وَخَشِيَ الرَّحْمَٰنَ بِالْغَيْبِ فَبَشِّرْهُ بِمَغْفِرَةٍ وَأَجْرٍ كَرِيمٍ
Your warning truly benefits only those who follow the Reminder and are in awe of the All-Merciful though they cannot see Him; give them good news of forgiveness and a noble reward

The previous verse described people upon whom the Prophet's warning has no effect. Now the Quran introduces another group: those who receive the divine message and allow its warning to guide and transform their lives.
The words “You warn only” do not mean that the Prophet addresses his warning exclusively to this group. His message reaches everyone. Rather, it is only those willing to recognise the truth who benefit from it.
The dhikr, or “Reminder”, here refers to the Quran. It awakens people from heedlessness and recalls truths they may have forgotten. Following the Reminder involves more than hearing or reciting its verses. We need to trust the message, turn towards it and be willing to shape our lives by it. Such following begins with an openness to truth and grows through putting it into practice.
The other characteristic of these people is khashyah of the All-Merciful in the unseen. Khashyah is reverent awe joined with awareness of God's greatness and a sense of responsibility before Him. The phrase bil-ghayb points to a person who believes in God and takes His promises seriously before the hidden realities of the life after death have become visible. Their reverence is not dependent on personally witnessing punishment or seeing the Hereafter. It grows from inner faith and understanding.
A striking detail is that this reverent awe is linked with the name “the All-Merciful”. God's name here emphasises the breadth of His mercy. This shows that awe of God does not contradict hope in His kindness. A believer recognises both divine greatness and justice while hoping for mercy and forgiveness. They do not become so complacent about mercy that they neglect their conduct, nor so afraid of punishment that they despair of being forgiven.
At the end, the tone moves from warning to good news: “Give them good news of forgiveness and a noble reward.” Those who have accepted the warning and embarked upon a life of devotion are invited to hope for forgiveness of their sins and a precious reward from their Lord. Forgiveness offers freedom from the burden of wrongdoing, while the noble reward promises a good outcome in the Hereafter.
The purpose of divine warning is not to leave people trapped in fear and despair. It is to awaken them and open a path towards mercy and genuine well-being. When someone responds with an open heart, the same warning that alerted them to danger becomes the beginning of the promise of divine forgiveness.
