A Muslim account of Jesus Christ's ascension from Tafsir al-`Ayashi:
Imam Ja`far as-Sadiq (a) said, "Jesus the son of Mary ascended whilst wearing a rabbinical garment made of wool spun from the yarn of Mary, the weaving of Mary, and the sewing of Mary. When he came to the heaven, it was called, 'O Jesus! Remove the frills of this world from yourself.'" (رفع عيسى بن مريم عليه بمدرعة (4) صوف من غزل مريم، ومن نسج مريم ومن خياطة مريم فلما انتهى إلى السماء نودى يا عيسى ألق عنك زينة الدنيا.)
This reference is actually very interesting. This expression, "rabbinical garment", has a very specific connotation in Jewish mysticism. There is a concrete term in Kabbalah, חלוקא דרבנן, precisely "rabbinical garment", which refers to the ethereal body of saints, somewhat similar to the body of people we see in the dream, visible and tangible yet not material in our crude sense. It is linked to Shechinah. Removing the garment may indicate ascension to higher levels beyond. When angels appeared in human form to Abraham, there were also wearing some type of "rabbinical garment". It works as a bridge between physical and spiritual.
Of course, Jesus in Muslim hadith literature is linked to themes of asceticism, and in this narration, Jesus is being asked to shed his attachment to this sentimental article of clothing before gaining proximity to God. Removing this rabbinical garment may be a symbol for Jesus' exit from the imaginal realm (which is between the fully material and the fully immaterial) and entry into the divine presence.
