It was narrated from Kathir bin Murrah that Abu Fatimah told him that he said: “Messenger of Allah صلی اللہ علیہ وآلہ وسلم, tell me of an action that I may do and persist in it.” The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said to him:
“You should emigrate, for there is nothing like it.” (Sahih)
