But, even though their bitter rivals failed to dent their title hopes, Smith warned that the rest of the SPL could still pose problems for his side.
He said: "I find it very difficult to overcome the teams in Scotland and I think the boys who manage the teams in Scotland do a great job.
"They make it difficult for the Old Firm to win matches. You would never find me claiming that [the title is over] because of the respect I have for the other teams. We'll have to continue to do as well as we have been doing."
Edu - who had an earlier effort disallowed within seconds of replacing the injured Lee McCulloch - claimed the decisive goal deep into injury time and Smith admits he was resigned to taking a point from the famous fixture by that stage in the game.
"I thought we weren't going to get the goal," he said.
