It is narrated from Sayyiduna Abdullah bin Unais (may Allah be pleased with him) that he and Sayyiduna Umar bin Khattab (may Allah be pleased with him) had a discussion on the topic of charity. Sayyiduna Umar (may Allah be pleased with him) said: "Did you hear that when the Messenger of Allah (peace and blessings of Allah be upon him) was mentioning the betrayal of charity, he said: 'Whoever betrays (from charity) a camel or a goat, then on the Day of Resurrection he will bring it carrying it on his back.'?" Sayyiduna Abdullah bin Unais (may Allah be pleased with him) said: Why not.

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: The Messenger of Allah (peace and blessings be upon him) sent Sayyiduna Sa’d bin Ubadah (may Allah be pleased with him) to collect zakat and said:“Sa’d! Beware, lest you come on the Day of Resurrection carrying a camel on your back while it is groaning.”Upon hearing this (warning), Sa’d said: I do not accept this responsibility, please excuse me. The Prophet (peace and blessings be upon him) excused him.
