Surah Yunus, Ayat 9-10

Ayat 9. Verily, those who believe [in the Oneness of Allah along with the six articles of Faith, i.e. to believe in Allah, His Angels, His Books, His Messengers, Day of Resurrection, and Al-Qadar (Divine Preordainments) - Islamic Monotheism], and do deeds of righteousness, their Lord will guide them through their Faith; under them will flow rivers in the Gardens of delight (Paradise).

Ayat 10. Their way of request therein will be Subhanaka Allahumma (Glory to You, O Allah!) and Salam (peace, safe from each and every evil) will be their greetings therein (Paradise)! and the close of their request will be: Al-Hamdu Lillahi Rabbil-'Alamin [All the praises and thanks are to Allah, the Lord of 'Alamin (mankind, jinns and all that exists)]. 

Hazrat Abu Musa (May Allah be pleased with him) reported: The Prophet [SAWW](PBUH) said, "The honest Muslim trustee who carries out duties assigned to him (in another narration he said, "Who gives''), and he gives that in full, with his heart overflowing with cheerfulness, to whom he is ordered, he is one of the two givers of charity". [Al-Bukhari Hadith # 1438].  

Lesson : as mentioned above in Surah Yunus Ayat 9. "do deeds of righteousness, their Lord will guide them through their Faith". This Hadith also mentions a very important principle to the effect that everyone must wholeheartedly perform the duty assigned to him by the state. If he is appointed custodian of the Bait-ul-Mal (public exchequer), he must fulfill his duty with utmost honesty. If he is not envious of anyone, nor harms anybody, nor behaves niggardly then he will be entitled to the same reward which will be due to the person who entrusted him that duty. Thus this Hadith enjoins every Muslim to perform his official duties wholeheartedly and to the best of his ability.
