Qabus bin al-Mukhariq (may Allah have mercy on him) said: Umm al-Fadl (may Allah be pleased with her) said: "O Messenger of Allah, I saw as if some of your limbs were in my house." He (peace and blessings be upon him) said: "It is good. Fatimah will give birth to a child, and you will nurse him." Then she gave birth to Hasan or Husayn, and I nursed him. Then one day I brought him to the Prophet (peace and blessings be upon him) and placed him in his (peace and blessings be upon him) lap, and he urinated, so I struck him on his shoulder. The Prophet (peace and blessings be upon him) said: "You have hurt my son, may Allah have mercy on you!"
