Attend the weekly congregational prayers on Fridays regularly .

This hadith emphasizes the importance of attending the weekly congregational prayer on Fridays. It is narrated by Abdullah b. Umar and Abu Huraira that they heard Allah's Messenger say on the planks of his pulpit that people must cease to neglect the Friday prayer or else Allah will seal their hearts and make them among those who are negligent. This means that if one does not attend this important congregational prayer then their hearts will be sealed off from understanding religious matters and they will become negligent in fulfilling their religious obligations. Therefore, it is important for Muslims to attend this weekly congregational prayer as it helps keep us connected with our faith and reminds us of our duties towards God Almighty.
