Patience is the foundation of the Believer’s faith, which has no other foundation. The one who has no patience has no faith, and if he has any, then it is only a little faith and it is very weak, and such a person worships Allaah as if he were upon the edge (i.e. in doubt): if good befalls him, he is content therewith; but if a trial befalls him he turns back on his face (i.e. reverts to disbelief after embracing Islam). He loses both this world and the Hereafter (cf. al-Hajj 22:11). All he gets from them is a losing deal.
The best life is attained by the Blessed through patience, and they rise to the highest degrees through their gratitude. So, they fly on the wings of patience and gratitude to gardens of delight (i.e., Paradise). That is the bounty of Allaah that He bestows upon whomsoever He wills, and Allaah is the Owner of Great Bounty. End quote from ‘Uddat al-Saabireen by Ibn al-Qayyim, p. 3-5.
‘Umar ibn ‘Abd al-‘Azeez (may Allaah be pleased with him) said: Allaah has not bestowed any blessing upon His slaves, then taken it away and replaced it with patience, but what He has compensated them with is better than what He has taken away.
