The World is three days: As for yesterday, it has vanished, along with all that was in it. As for tomorrow, you may never see it. As for today, it is yours, so work in it.
- Hassan al-Basri
Ease [yusr] and hardship ['usr] are the feathers that give strength to the wings of your faith [iman], so that your heart and your innermost being [sirr] can use them to fly to the door of your Lord (Almighty and Glorious is He).
- Shaykh 'Abd al-Qadir al-Jilani
