The Source of Traditions on Imam al-Riḍā (Vol 2) · Hadith 46 (#Ḥadīth #46)

46 - وَبِهذَا الإِسنادِ قالَ: قالَ رَسُولُ اللَّهِ صَلَّى اللهُعَلَيْهِ وَآلِهِ: لا تُضَيِّعُوا صَلاتِكُمْ فَإِنَّ من ضيع صَلاتَهُ حشرمَعَ قارون وَهامان وَكانَ حَقّاً عَلَى اللَّه أَن يُدخِلَهُ النَّارِمَعَ المُنافِقِين فالويل لِمَنْ لَمْ يحافظ عَلَى صَلاتَهُ وَأَداءَ سِنَةَ نَبِيِّهِ.

31-46 According to the same documentation, God’s Prophet (S) said, “Do not ruin your prayers. Whoever does so will be united with Qarun and Haman. Then it is the right of God to send him into Hell along with the hypocrites. Then woe be to those who do not guard their prayers and do not perform the Prophet’s tradition.”
