There is neither rest nor comfort of a lasting nature until one enters Paradise. This life is full of problems, trials, ordeals, sickness, and worries.
A colleague of mine from Nigeria told me that, when he was a child, his mother would wake him up during the last third of the night to pray. He would answer, “Mother, I want to rest a little.” She would say, “I am only waking you up for your comfort’s sake. O’ my son, when you enter Paradise you will find your repose.
