Musnad Ahmad 30:1714

Muhammad narrated to us, he said: Isma'il ibn Zakariyya narrated to us, from Suhayl ibn Abi Salih, from Abu Hurayrah, who said: The Messenger of Allah, may Allah bless him and grant him peace, said: "Whoever says when he reaches the morning and when he reaches the evening: 'Glory be to Allah and by His praise' (Subhan Allah wa bi-hamdihi) one hundred times, no one will come on the Day of Resurrection with anything better than what he has brought, except for someone who said the same as what he said, or added to it."
