Musnad Abu Ya'la al-Mawsili 6:22

Harun ibn Ma'ruf narrated to us, Abdullah ibn Wahb narrated to us, Amr ibn al-Harith informed me that Sa'id ibn Abi Hilal narrated to him, from Aisha bint Sa'd ibn Abi Waqqas, from her father, that he entered with the Messenger of Allah, may Allah bless him and grant him peace, upon a woman, and in front of her were date pits and pebbles with which she was performing tasbih (glorifying Allah). He said: "Shall I inform you of what is easier for you than this, or better? Say: 'Glory be to Allah (SubhanAllah) the number of what He created in the heaven, and glory be to Allah the number of what He created in the earth, and glory be to Allah the number of what is between them, and glory be to Allah the number of what He is the Creator of.' And say: 'Allah is the Greatest (Allahu Akbar) like that, and praise be to Allah (Alhamdulillah) like that, and there is no god but Allah (La ilaha illa Allah) like that, and there is no power except by Allah (La hawla wa la quwwata illa billah) like that.'"
