quran:67:12 –

Indeed, those who fear their Lord unseen will have forgiveness and great reward.  

Assuredly those who fear their Lord in secret, while they are absent from people’s eyes, being obedient to Him in secret, such that openly ˹before people˺ it is all the more likely ˹that they fear their Lord˺ — there will be for them forgiveness and a great reward, namely, Paradise.
القرآن:٦٧:١٢ –

إِنَّ الَّذِينَ يَخْشَوْنَ رَبَّهُمْ بِالْغَيْبِ لَهُمْ مَغْفِرَةٌ وَأَجْرٌ كَبِيرٌ  

{إن الذين يخشون ربهم} يخافونه {بالغيب} في غيبتهم عن أعين الناس فيطيعونه سرا فيكون علانية أولى {لهم مغفرة وأجر كبير} أي الجنة.
