It was narrated from Abu Al-Ja'd Ad-Damri-who was a Companion of the Prophet ﷺ- that the Prophet ﷺ said: "Whoever missed three jumu'ahs out of negligence, Allah will place a seal over his heart".
The hadith also teaches us about accountability and responsibility towards our obligations as Muslims. We must be mindful of our duties towards God and not take them lightly or neglect them due to laziness or carelessness as this can lead to serious consequences in both this life and the hereafter. Furthermore, we should strive to be consistent with our worship so we can reap its benefits both spiritually and physically throughout our lives.
