Shama-il Tirmidhi Chapter 035, Hadith Number 006 (230).

Hasan Basri radiyallahu anhu says that an old woman came to Rasoolullah sallallahu alaihe wasallam and made a request, O’ Messenger of Allah make Dua that Allah grants me entrance into Jannah.

Rasoolullah sallallahu alaihe wasallam replied, O’ Mother, an old woman cannot enter Jannah. That woman started crying and began to leave. Rasoolullah sallallahu alaihe wasallam said, Say to the woman that one will not enter in a state of old age, but Allah will make all the women of Jannah young virgins. Allah Ta’aala says, Lo! We have created them a (new) creation and made them virgins, lovers, equal in age. (Surah Waaqi’ah, 35-37).
