Abu Dharr reported,

I came upon the Prophet ﷺ while he was sitting in the shade of the Kaabah. When he saw me, he said, "By the Lord of the Kaabah, they are the greatest losers!"I came forward and sat down, but I could not stay still. I stood up and said, "Messenger of Allah, may my father and mother be ransomed for you, who are they?"He replied, "They are those with the most wealth, except for the one who gives like this, and like this, and like this," gesturing in front of him, behind him, to his right, and to his left, "and few are they! There is no owner of camels, cattle, or sheep who fails to pay their zakat but that they will come on the Day of Resurrection larger and fatter than they ever were, goring him with their horns and trampling him with their hooves. Each time the last of them passes over him, the first returns to him again, until judgment is passed among the people."

عن أبي ذر قال

انتهيت إلى النبي ﷺ وهو جالس في ظل الكعبة. فلما رآني قال: هم الأخسرون ورب الكعبة! قال: فجئت حتى جلست فلم أتقار أن قمت فقلت: يا رسول الله فداك أبي وأمي من هم؟ قال: هم الأكثرون أموالا إلا من قال هكذا وهكذا وهكذا من بين يديه ومن خلفه وعن يمينه وعن شماله، وقليل ما هم! ما من صاحب إبل ولا بقر ولا غنم لا يؤدي زكاتها إلا جاءت يوم القيامة أعظم ما كانت وأسمنه تنطحه بقرونها وتطوه بأظلافها كلما نفدت أخراها عادت عليه أولاها حتى يقضى بين الناس.
