Abu Kabshah reported: The Messenger of Allah, peace and blessings be upon him, said, “I swear an oath by Allah on three qualities and I will tell you about them, so memorize them: the wealth of a servant is not decreased by charity, a servant is not wronged by oppression and he endures it patiently but that Allah increases him in honor, and no servant opens the door of begging but that Allah opens for him the door of poverty.”

عن أبي كَبْشَة الْأَنَّمَارِيّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ ثَلَاثَةٌ أُقْسِمُ عَلَيْهِنَّ وَأُحَدِّثُكُمْ حَدِيثًا فَاحْفَظُوهُ مَا نَقَصَ مَالُ عَبْدٍ مِنْ صَدَقَةٍ وَلَا ظُلِمَ عَبْدٌ مَظْلَمَةً فَصَبَرَ عَلَيْهَا إِلَّا زَادَهُ اللَّهُ عِزًّا وَلَا فَتَحَ عَبْدٌ بَابَ مَسْأَلَةٍ إِلَّا فَتَحَ اللَّهُ عَلَيْهِ بَابَ فَقْرٍ
