It was narrated that ‘Amr bin Aws said: “A man of Thaqlf told us that he heard the caller of the Messenger of Allah صلی اللہ علیہ وآلہ وسلم ti on a rainy night during a journey saying: ‘Hayya ‘ala as-salah, Hayya ‘ala al-falah, sallafi rihalikum (Come to prayer, come to prosperity, pray in Your dewellings).” (Sahih).
