From Sahih Muslim (Hadith 6926):
Abu Dharr reported that Allah's Messenger (ﷺ) said:Should I not inform you about the words liked most by Allah? I said: Allah's Mes- senger, do inform me about the words liked most by Allah. He said: Verily, the words liked most by Allah are:" hallowed be Allah and praise is due to Him
