Umm Malik used to send clarified butter as a gift to the Prophet ﷺ in a leather flask of hers. Her sons would come to her asking for something to eat with their bread when they had nothing in the house, so she would turn to the very flask in which she sent gifts to the Prophet ﷺ and find clarified butter in it. It kept providing the food of her household until she squeezed it out.She came to the Prophet ﷺ, and he asked, "Did you squeeze it?"She replied, "Yes."He said, "Had you left it alone, it would have kept on providing."
و حدثني سلمة بن شبيب حدثنا الحسن بن أعين حدثنا معقل عن أبي الزبير
أن أم مالك كانت تهدي للنبي ﷺ في عكة لها سمنا فيأتيها بنوها فيسألون الأدم وليس عندهم شيء فتعمد إلى الذي كانت تهدي فيه للنبي ﷺ فتجد فيه سمنا فما زال يقيم لها أدم بيتها حتى عصرته فأتت النبي ﷺ فقال عصرتيها قالت نعم قال لو تركتيها ما زال قائما
