"Whoever missed three jumu'ahs out of negligence, Allah will place a seal over his heart."  

عَنْ أَبِي الْجَعْدِ الضَّمْرِيِّ وَكَانَتْ لَهُ صُحْبَةٌ عَنِ النَّبِيِّ ﷺ قَالَ مَنْ تَرَكَ ثَلاَثَ جُمَعٍ تَهَاوُنًا بِهَا طَبَعَ اللَّهُ عَلَى قَلْبِهِ  

The Messenger of Allah ﷺ said: "Whoever misses jumu'ah three times with no cogent excuse, Allah (SWT) will place a seal on his heart."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ مَنْ تَرَكَ الْجُمُعَةَ ثَلاَثًا مِنْ غَيْرِ ضَرُورَةٍ طَبَعَ اللَّهُ عَلَى قَلْبِهِ  

He heard Ibn Abbas and Ibn Umar narrate that while he was on the minbar, the Messenger of Allah ﷺ said: "People should stop neglecting Jumu'ah or Allah will place a seal on their hearts and they will be deemed as being among the negligent."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ وَهُوَ عَلَى أَعْوَادِ مِنْبَرِهِ لَيَنْتَهِيَنَّ أَقْوَامٌ عَنْ وَدْعِهِمُ الْجُمُعَاتِ أَوْ لَيَخْتِمَنَّ اللَّهُ عَلَى قُلُوبِهِمْ وَلَيَكُونَنَّ مِنَ الْغَافِلِينَ  

The Prophet ﷺ said: "Going to Jumu'ah is obligatory for everyone who has reached the age of puberty.'"  

عَنْ حَفْصَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ النَّبِيَّ ﷺ قَالَ رَوَاحُ الْجُمُعَةِ وَاجِبٌ عَلَى كُلِّ مُحْتَلِمٍ
