Anas bin Malik reported,

A son of Abu Talha was sick. Abu Talha went out, and the boy passed away. When Abu Talha returned, he asked, "How is my son?"Umm Sulaym replied, "He is more at peace than he has been."She then brought him his evening meal, and he ate. Afterwards he was intimate with her. When he had finished, she said, "Bury the boy."In the morning, Abu Talha went to the Messenger of Allah ﷺ and informed him of what had happened. The Prophet ﷺ asked, "Were you intimate last night?"He replied, "Yes."The Prophet ﷺ said, "Allah, bless them both."She gave birth to a boy. Abu Talha said to me, "Look after him until you bring him to the Prophet ﷺ." So he brought him to the Prophet ﷺ, and Umm Sulaym sent some dates with him.The Prophet ﷺ took the child and asked, "Is there anything with him?"They said, "Yes, some dates."The Prophet ﷺ took the dates, chewed them, then took some from his own mouth and placed it into the child's mouth, rubbing it against his palate. He named him Abdullah.Muhammad bin al-Muthanna narrated to us, Ibn Abu Adi narrated to us from Ibn Awn from Muhammad from Anas, and he related the hadith.
