فَإِنَّ مَعَ الْعُسْرِ يُسْرًا إِنَّ مَعَ الْعُسْرِ يُسْرًا
With hardship comes ease; indeed, with hardship comes ease.
Ash-Sharḥ 94:5 begins with fa-inna, while 94:6 begins with inna. Their repeated assurance strengthens the message, and the first verse’s fāʾ visibly connects the statement to what precedes.
It is safe to identify reinforcement through repetition. A fixed numerical formula about how many particular eases must accompany a hardship cannot be imposed on word repetition alone without further interpretive evidence.
