The Oman international, who is on a season-long loan from Bolton, has impressed for Wigan.
The Wigan boss said: “We are all pleased Ali is with us and we will try to keep him here as long as we can.
“He has been a breath of fresh air since he came in. He loves his football and has high standards.
“It is very rare that a foreign player has real knowledge of the Premier League but Ali has developed that during his time in England.
“Since his first game he has been performing at a very good level. He has been very consistent and assured.
“He has developed a great relationship with the back four and that is always important. But the main thing is he is enjoying his football.”
