The proof that Jibril is the Ruh Al-Qudus is the statement of Ibn Mas`ud in explanation of this Ayah. This is also the view of Ibn `Abbas, Muhammad bin Ka`b, Isma`il bin Khalid, As-Suddi, Ar-Rabi` bin Anas, `Atiyah Al-`Awfi and Qatadah. Additionally, Allah said,

﴿نَزَلَ بِهِ الرُّوحُ الاٌّمِينُ - عَلَى قَلْبِكَ لِتَكُونَ مِنَ الْمُنْذِرِينَ ﴾

(Which the trustworthy Ruh (Jibril) has brought down. Upon your heart (O Muhammad ) that you may be (one) of the warners) (26:193-194).

Al-Bukhari recorded `A'ishah saying that the Messenger of Allah erected a Minbar in the Masjid on which Hassan bin Thabit (the renowned poet) used to defend the Messenger of Allah (with his poems). The Messenger of Allah said,

«اللَّهُمَّ أَيِّدْ حَسَّانَ بِرُوحِ الْقُدُسِ كَمَا نَافَحَ عَنْ نَبِيِّك»

(O Allah! Aid Hassan with Ruh Al-Qudus, for he defended Your Prophet.)

Abu Dawud recorded this Hadith in his Sunan as did At-Tirmidhi who graded it Hasan Sahih. Further, Ibn Hibban recorded in his Sahih that Ibn Mas`ud said that the Prophet said,

«إِنَّ رُوحَ الْقُدُسِ نَفَثَ فِي رُوعِي أَنَّهُ لَنْ تَمُوتَ نَفْسٌ حَتَّى تَسْتَكْمِلَ رِزْقَهَا وَأَجَلَهَا، فَاتَّقُوا اللهَ وَأَجْمِلُوا فِي الطَّلَب»

(Ruh Al-Qudus informed me that no soul shall die until it finishes its set provisions and term limit. Therefore, have Taqwa of Allah and seek your sustenance in the most suitable way.)
