Scholars agree on the concept of the descent of Jesus. Thus, it is one of those concepts on which there is consensus (ijma) in the Ummah:
Imam Ibn Jarir Tabari in his Jami' al-Bayan wrote:
والاجماع على انه حي في السماء وينزل ويقتل الدجال ويؤيد الدين.
The consensus is that Jesus is alive in the heavens and will descend and kill the Dajjal and support the religion. (2/52)
Imam Ibn Atiyah in Al-Bahr al-Muhit states:
وأجمعت الأمة على ما تضمنه الحديث المتواتر من: أن عيسى في السماء حي، وأنه ينزل في آخر الزمان، فيقتل الخنزير.
The entire Ummah agrees, based on the mutawatir hadiths, that Jesus is alive in the heavens and will descend in the last era and kill the pig. (2/360)
Imam Ash’ari writes:
وأجمعت الأمة على أن اللّٰه سبحانه رفع عيسى صلى اللّٰه عليه وسلم إلى السماء.
The Ummah has consensus that Allah Almighty raised Jesus to the heavens. (Al-Ibanah 'an Usul al-Diyanah 1/115)
In Al-Talkhis al-Khabir, it is stated:
فاتفق أصحاب الأخبار والتفسير على أنه رفع ببدنه حيا.
The historians and interpreters agree that Jesus was raised to heaven with his body alive. (3/462)
Imam Shams al-Din Saffarini, a renowned scholar of the Hanbali school, writes:
واما الاجماع فقد اجتمعت الامة علي نزوله ولم يخالف فيه احد من اهل الشريعة وانما انكر ذلك الفلاسفة والملاحدة مما لا يعتد بخلافة وقد انعقد اجماع الامة علي انه ينزل ويحكم بهذه الشريعة المحمديه.
As for consensus, the Ummah is united on his [Jesus’s] descent, and no one among the people of the Shariah has opposed it. Only philosophers and atheists have denied it, whose opposition is not considered significant in religious matters. The consensus of the Ummah has been established that he [Jesus] will descend and rule according to this Muhammadan Shariah. (Sharh Aqidah Saffarini 2/90)
