Hadith Takhrij«أخرجه الترمذي، أبواب الصلاة، باب ما جاء في مبادرة الصبح بالوتر، حديث:469.»
The word "kull" is nominative because it is the subject (fa‘il) of "dhahaba," and "al-witr" is conjoined (ma‘tuf) to the word "kull," therefore it too will be nominative.

´Ibn Umar narrated that :` Allah's Messenger said: "When Fajr begins, then every Salat of the night and Al-Witr have gone, so perform Al-Witr before Fajr begins."
Shaykh Dr. Abdur Rahman Freywai
1: It has been mentioned in the footnote to the previous hadith that many of the noble Companions (radi Allahu anhum) and eminent Imams (rahimahumullah) hold the view that the missed witr prayer should be made up (qada), and this is the preferred opinion. This is because if one does not perform the witr, the even-numbered units (rak‘ahs) of the Sunnah and supererogatory (nawafil) prayers will not become odd-numbered, and Allah knows best.
