سنن النسائي 1331

It was narrated from 'Imran bin Husain that:The Prophet (ﷺ) prayed three (rak'ahs) then said the taslim. Al-Khirbaq said: "You prayed three." So he led them in praying the remaining rak'ah, then he said the taslim, then he did the two prostrations of forgetfulness, then he said the taslim (again)

Rapporté par 'Imran bin Husain : Le Prophète (ﷺ) a prié trois unités, puis a fait le taslim. Al-Khirbaq dit : "Tu as prié trois." Alors il leur fit accomplir la rak'ah manquante, puis il fit le taslim, ensuite il fit deux prosternations de l’oubli, puis il fit de nouveau le taslim
