Silsilat al-Ahadith al-Sahihah

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.
