Yazid ibn Abd Rabbih narrated to us, al-Walid ibn Muslim narrated to us, from Ibn Jabir, Isma'il ibn 'Ubayd Allah narrated to me, from Karimah bint al-Hash-has al-Muzaniyyah, she said: I heard Abu Hurayrah saying in the house of Umm al-Darda': The Messenger of Allah, may Allah bless him and grant him peace, said: "Allah, the Mighty and Majestic, said: 'I am with My servant when he remembers Me, and his lips move with Me.'"
