Ibn Abbas narrated that the Messenger of Allah (ﷺ) said:
" He is not one of us who does not have mercy upon our young, respect our elders, and command good and forbid evil."
Mujahid said:
"Ibn Abbas was asked about a man who fasted during the day and stood (in prayers) during the night, but he did not attend the Friday prayer nor congregational prayer. He replied: 'He is in the Fire.'"
