Chapter: Orang yang lupa mengerjakan shalat hendaklah mengerjakannya ketika dia ingat dan tidak mengulangi kecuali shalat yang tertinggal itu

The Prophet (ﷺ) said, "If anyone forgets a prayer he should pray that prayer when he remembers it. There is no expiation except to pray the same." Then he recited: "Establish prayer for My (i.e. Allah's) remembrance." (20.14).
