Abu Humaid bin Sa'd As-Sa'idi (May Allah bepleased with him) reported:
The Prophet ﷺ employed a man from the tribe of Al-Azd named Ibn Lutbiyyah as collector of Zakat. When the employee returned (with the collections) he said: "(O Prophet ﷺ!) This is for you and this is mine because it was presented to me as gift." Messenger of Allah ﷺ rose to the pulpit and praised Allah and extolled Him. Then he said, "I employ a man to do a job and he comes and says: 'This is for you and this has been presented to me as gift'? Why did he not remain in the house of his father or the house of his mother and see whether gifts will be given to him or not? By Allah in Whose Hand is the life of Muhammad, if any one of you took anything wrongfully, he will bring it on the Day of Resurrection, carrying it on (his back), I will not recognize anyone of you, on the Day of Resurrection with a grunting camel, or a bellowing cow, or a bleating ewe." Then he raised his hands till we could see the whiteness of his armpits. Then he said thrice, ''O Allah ! have I conveyed (Your Commandments)".

وعن أبي حميد عبد الرحمن بن سعد الساعدي رضي الله عنه قال: استعمل النبي رجلاً من الأزد يقال له: ابن اللتبية على الصدقة، فلما قدم قال : هذا لكم، وهذا أهدي إلي، فقام رسول الله ﷺ على المنبر، فحمد الله وأثنى عليه، ثم قال: “أما بعد فإني أستعمل الرجل منكم على العمل مما ولاني الله، فيأتي فيقول: هذا لكم، وهذا هدية أهديت إلي، أفلا جلس في بيت أبيه وأمه حتى تأتيه هديته إن كان صادقًا، والله لا يأخذ أحد منكم شيئًا بغير حقه إلا لقى الله تعالى، يحمله يوم القيامة، فلا أعرفن أحدًا منكم لقي الله يحمل بعيرًا له رغاء، أو بقرة لها خوار، أو شاة تيعر” ثم رفع يديه حتى رؤي بياض إبطيه فقال : "اللهم هل بلغت" ثلاثا ((متفق عليه)) .
