Hadith on Friday: Allah seals hearts of those who neglect Friday prayer

Umar ibn al-Khattab reported: The Messenger of Allah, peace and blessings be upon him, said, “Whoever hears the announcement of Friday prayer and he does not come, then he hears it again and does not come, then he hears it again and does not come, Allah will place a seal over his heart and turn his heart into the heart of a hypocrite.”

عن عمر بن الخطاب قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ سَمِعَ النِّدَاءَ يَوْمَ الْجُمُعَةِ فَلَمْ يَأْتِهَا ثُمَّ سَمِعَهُ فَلَمْ يَأْتِهَا ثُمَّ سَمِعَهُ فَلَمْ يَأْتِهَا طَبَعَ اللَّهُ عَلَى قَلْبِهِ وَجَعَلَ قَلْبَهُ قَلْبَ مُنَافِقٍ
