Allah—Mighty and Majestic—said: [‏وَمَنْ يَغْلُلْ يَأْتِ بِمَا غَلَّ يَوْمَ الْقِيَامَةِ‏]

Sayyiduna ‘Adi bin ‘Umayrah Kindi (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said:“Whoever is appointed by us to do any work and then conceals from it even a needle or anything less than that, it is a betrayal, and he will bring it with him on the Day of Resurrection.”Upon hearing this, a black Ansari man— as if I am seeing him— said,“O Messenger of Allah (peace and blessings be upon him), take back your responsibility from me.”The Prophet (peace and blessings be upon him) asked,“Why?”He replied,“Because I heard you say such and such.”The Prophet (peace and blessings be upon him) said,“And I say this: When we appoint someone to a responsibility, he should bring forth whatever little or much he has, then take what is given to him and refrain from what is withheld from him.”
