Musnad Ahmad 32:91

Musa ibn Hilal narrated to us, Hisham narrated to us, from Ibn Sirin, from Anas ibn Malik, who said: Abu Talha married Umm Sulaym, and she is the mother of Anas and al-Bara’. She bore him a child whom he loved—then he mentioned the hadith—and the Messenger of Allah (peace and blessings of Allah be upon him) said: "Did you spend the night as newlyweds while he was by your side?" He said: "Yes, O Messenger of Allah." He said: "May Allah bless you both in your night."
