The Shi’a will enter Heaven with the Prophet (s), Hadhrath Ali (as) and the pure Imams
Ibn Hajr records this tradition from Imam Tabarani:
“O Ali four people will enter heaven first of all. You Hasan Hussain your descendents and me will follow us and our wives will follow our descendents and our Shi’a will be to the left and right of us”.
The Prophet (s) promised to meet Ali (as) and his Shi’a at the fountain of Kawthur
Hadhrath Ali narrates in Tafsir Durre Mansur, Volume 6 page 379 (Cairo edition)
“Have you not heard this verse “Their reward from their Lord shall be everlasting gardens, below which flow rivers, they will abide there forever”? This verse refers to you and you Shi’a, I promise you that I will be meet you at the Fountain of Kawthur”.
