It was narrated from Salman Al-Khair that the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: “Whoever guards Riba! (the frontier) for one day and one night, will be given a reward like that for fasting and praying Qiyam for a month, and whoever dies at Riba! (guarding the frontier) will be rewarded, and he will be given provision, and he will be kept safe from Al-Fattan ''. (Sahih)
