Musannaf Ibn Abi Shayba 21:341

Waki’ narrated to us, from Mis’ar, from ‘Abd al-Malik ibn Maysarah, from Hilal, from Umm al-Darda’, who said: Whoever says one hundred times in the morning and one hundred times in the evening, "There is no god but Allah, alone, He has no partner; to Him belongs the dominion, and to Him belongs the praise, and He is capable of all things," no one will come on the Day of Resurrection with the like of what he has come with, except for one who said the like of them or added more.
