Is it a sin to avoid an abusive father?
Some people are tested with different types of calamities. Some are tested with cancer. Others face drought and famine. There are those who sleep and wake up under bombshells. Some see their mothers and sisters being raped and brutally killed in front of them, not to mention the homeless and those who drown at sea looking for a better place to live in!Would you like to exchange places with any of the above.
Allah has tested you with such a father who is your gateway to Paradise. Being undutiful or disrespectful would surely prevent you from entering paradise.
The choice is yours!
