Do for this life as if you live forever, do for the afterlife as if you will die tomorrow.
Ali ibn Abi TalibWhoever desires Paradise, proceeds towards goodness; whoever fears Hell, refrains from the impulses of passions; whoever believes firmly in death, detests wordly life; and whoever recognises the worldly life, the trials and tribulations (of life) become slight for him.
