From Sahih Muslim (Hadith 6843):
Abu Huraira reported Allah's Messenger (ﷺ) as saying:He who recites in the morning and in the evening (these words):" Hallowed be Allah and all praise is due to Him" one hundred times, he would not bring on the Day of Resurrection anything excellent than this except one who utters these words or utters more than these words
