Musnad Ahmad 1304:29

Hashim narrated to us, he said: Abd al-Hamid narrated to us, he said: Shahr narrated to me, he said: I heard Asma bint Yazid al-Ansariyyah narrating; she claimed that the Messenger of Allah (peace and blessings of Allah be upon him) passed by in the mosque one day, and a group of women were sitting. He gestured with his hand toward them with the greeting, and said: "Beware of the ingratitude toward the benefactors, beware of the ingratitude toward the benefactors." One of them said: "O Messenger of Allah, I seek refuge in Allah, O Prophet of Allah, from the ingratitude toward the blessings of Allah." He said: "Yes, indeed, one of you may have her period of being unmarried last long, and her remaining unmarried last long, then Allah provides her with a husband, and grants her children and the coolness of the eyes. Then she becomes angry with an anger, and swears by Allah that she has never seen an hour of good from him at all. That is from the ingratitude toward the blessings of Allah the Almighty and Majestic, and that is from the ingratitude toward the benefactors."
