The Messenger of Allah ﷺ said, "There is no owner of camels, cattle, or sheep who fails to pay their zakat except 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. Whenever the last of them passes over him, the first returns to him again, until judgment is passed among the people."
أخبرنا محمد بن عبد الله بن المبارك قال حدثنا وكيع قال حدثنا الأعمش عن المعرور بن سويد
قال رسول الله ﷺ ما من صاحب إبل ولا بقر ولا غنم لا يؤدي زكاتها إلا جاءت يوم القيامة أعظم ما كانت وأسمنه تنطحه بقرونها وتطؤه بأخفافها كلما نفدت أخراها أعادت عليه أولاها حتى يقضى بين الناس
