It was narrated from 'Abdur-Rahman bin ‘Abdullah bin Mas'ood, from his father, that

The Prophet (ﷺ) said: “May Allah curse the one who consumes riba, the one who pays it, the two who witness it and the one who writes it down." And he said: "Riba and zina never become widespread among a people but they bring down the punishment of Allah upon themselves."
