Being people of Jannah

The people of Jannah did sleep, but not that much. They would wake up and pray tahajjud, and do istighfar during suhoor time. They were concerned about the akhirah, over the enjoyment of the dunya – though that isn’t haram to enjoy yourself as long as it’s within the boundaries of what is permissible. However, the dunya wasn’t their main concern: Allah was their target.
