Hadith

 وَ بِهَذَا اَلْإِسْنَادِ عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ زَيْدٍ عَنْ أَبِي عَبْدِ اَللَّهِ ع قَالَ : لَنْ تَكُونُوا مُؤْمِنِينَ حَتَّى تَكُونُوا مُؤْتَمَنِينَ وَ حَتَّى تَعُدُّوا نِعْمَةَ اَلرَّخَاءِ مُصِيبَةً وَ ذَلِكَ أَنَّ اَلصَّبْرَ عَلَى اَلْبَلاَءِ أَفْضَلُ مِنَ اَلْعَافِيَةِ عِنْدَ اَلرَّخَاءِ.

 (The same previous series of relaters)… from Mohammed bin Ahmed from Zaid that Abu Abdullah (a) said: You will not be considered as believers before you become trustworthy and regard the favor of luxury as misfortune. In fact, to be steadfast against misfortunes is better than to enjoy good health with luxury.
