The sentence you have probably heard

If you cannot wake for tahajjud, your heart is diseased. If you really loved Allah you would be up.

It gets said in reminders, in group chats and in your own head at four in the morning, and it does a specific kind of damage to someone who is not sleeping. It turns the sleep problem into a verdict about you. Then, because you now dread the night, the sleep gets worse, and the worse it gets the more the verdict seems to be confirmed.

What follows is what the Qur'an and the sound reports actually do with a night that did not happen. It is close to the opposite of that sentence.
