When someone neglects the etiquette of being awake, their wakefulness becomes sleep. When someone abides by the etiquette of sleep, however, their sleep becomes wakefulness.
Much harm is caused to Muslims by their hearts being asleep. Being distracted by other than Him is, in reality, sleep. If we realised the truth, we would wake up.
Sleeper, wake up! Muslims are in a deep sleep. That is why disbelievers being given power over Muslims can be likened to the animals of the jungle playing around a sleeping lion.
