Al-Kāfi|Volume 3|Book 4|Chapter 31
6ـ وَبِهَذَا الإِسْنَادِ عَنْ يُونُسَ عَنْ وَهْبِ بْنِ عَبْدِ رَبِّهِ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ مَنْ تَرَكَ الْقُنُوتَ رَغْبَةً عَنْهُ فَلاَ صَلاَةَ لَهُ.
6. Through the same chain of narrators as that of the previous Hadith the following is narrated from Yunus from Wahab ibn “Abd Rabbihi who has said the following: “Abu ‘Abd Allah عليه السلام, has said, ‘Whoever omits Qunut (supplication after recitation in second Rak‘at) in dislike his Salah (prayer) is not anything.’”
