“The affection to us “Ahl al Bayt”
مَنْ رَزَقَهُ اللَّهُ حُبَ الْأَئِمَّةِ مِنْ أَهْلِ بَیْتِی فَقَدْ أَصَابَ خَیْرَ الدُّنْیَا وَ الْآخِرَةِ فَلَا یَشُکَّنَّ أَحَدٌ أَنَّهُ فِی الْجَنَّةِ»
If The Almighty God grants someone the affection to Imams (pbu th),
they will has come to all the good of the world and the Hereafter. So, no one doubts such a person will enter in heaven.
