Although the words "endurance" and "patience" are often tied together, they actually represent two different concepts. Endurance has specific bounds and these vary according to the individual. When those bounds are exceeded, a person may abandon his or her moderate and calm approach in favor of various behavioral defects. Patience on the other hand is a moral virtue stemming from fear of Allah, one which does not change with circumstances or events. It is only possible to be patient in the face of troubles or events by comprehending the infinite might of Allah and putting one's trust in Him by seeing the good in all that He creates. True patience is therefore a feature peculiar to believers and an element of good moral values which people who fail to live by the values of the Qur'an can never achieve. Believers are described as patient and submissive in the Qur'an:
[Believers are] those who are patient and put their trust in their Lord. (Surat an-Nahl, 42)
Those who patiently persevere in seeking the face of their Lord, and perform prayer and give from the provision We have given them, secretly and openly, and stave off evil with good, it is they who will have the Ultimate Abode. (Surat ar-Ra'd, 22)
