Spend little on my shroud, for if I have good awaiting me with Allah, He will give me what is better than that shroud.  If it is the other destination, I will be rid of that shroud in a haste.  Also, do not make my grave very wide, for if I have good awaiting me with Allah, He will make my grave as wide as my sight reaches.  If it was the other, He will make my grave come together on me until my ribs cross each other [ie. ‘Dhaghtatu al-Qabr; the squeeze in the grave].

—‘Umar ibn al-Khaṭṭāb [d. 23H/644CE]
