Hawzah News Agency -  Imam al-Hasan (AS) said:

بِالعَقلِ تُدرَكُ الدّارانِ جَميعاً، ومَن حُرِمَ مِنَ العَقلِ‏ حُرِمَهُما جَميعاً.

‘Both the abodes [of the world and the Hereafter] are grasped by the intellect, and whoever is deprived of the intellect is deprived of them both.’

Kashf al-Ghamma, v. 3, p. 197
