Asma', the daughter of Yazid al-Ansari, said, "The Prophet ﷺ passed by me while I was with some young slavegirls belonging to me. He greeted us and said, 'Beware of the ingratitude of those with blessings.' I was the boldest of them in coming forward to question him and I said, 'Messenger of Allah, what is the ingratitude of those with blessings?' He replied, 'Perhaps one of them with remain unmarried for a long time with her parents and then Allah provides her with a husband and provides her with children from him and then she gets angry and is ungrateful and says, "I have never seen any good at all from you."'"
