From Sahih Muslim (Hadith 6467):
Abu Sa'id Khudri reported Allah's Apostle (ﷺ) as saying:A time would come for the people when groups of people would set out for fighting in the cause of Allah and it would be said to them: Is there one amongst you who saw Allah's Messenger (ﷺ)? And they would say: Yes, and they would be victorious. Then the people would set out for fighting in the cause of Allah and it would be said to them: Is there one amongst you who saw those (who have had the privilege of sitting in the company of Allah's Messenger (ﷺ)? And they would say: Yes, and victory would be granted to them. Then a group of persons would set out for fighting in the cause of Allah and it would be said to them: Is there one amongst you who saw one of those who saw those who (had the privilege) of sitting in the company of Allah's Messenger (ﷺ)? And they would say: Yes, and the Victory would be granted to them
