The Source of Traditions on Imam al-Riḍā (Vol 2) · Hadith 65 (#Ḥadīth #65)

65 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: حُرِّمَتِ الجَنَّةُ عَلى مَن ظَلَمَ أَهْلَ بَيْتِي وَعَلى مَن قاتَلَهُم، وَعَلَى المُعِينِ عَلَيْهِمْ وَعَلَى مَن سَبَّهُم، اُولئِكَ لا خَلاقَ لَهُم فِي الآخِرَةِ وَيُكَلِّمُهُم اللَّهُ، وَلا يَنْظُرُ إِلَيْهِم يَوْمَ القِيامَةِ وَلا يُزِكِّيهِم وَلَهُم عَذابٌ ألِيمٌ.

31-65 According to the same documentation, God’s Prophet (S) said, “Paradise is forbidden for those who oppress the members of my Household, those who kill them, those who assist their oppressors or murderers, and those who insult them. They will have no share of any good in the Hereafter and God will neither talk to them or look upon them on the Resurrection Day. He will not purify them. There will be a painful punishment for them.”
