Abu Amr Shaybani reported, that a man asked Sayyidina Ibn Masud (RA), "Which deed was the best"? He said, "I had put the same question to Allahs Messenger ﷺ and he said, "To offer Salah during the mustahabb time for it." Then I asked him, what was besides that and he said that it was to serve parents. When I asked him about anything besides, he said it was to wage jihad in Allahs path."
