That is the first time. Not all the times
iirc, there was an episode in Indigo League where Ash and friends were on the S.S. Anne and there was some inconvenience. Like, it was sinking or something. “Team Ash” and Team Rocket agreed to help each other off the boat (I think)
And then gyrados evolved and alomst killed them
He was helped by team rocket
For winning the rainbow badge .
In  which he was disguised as Ashley. A girl trainer, wanna know more watch the episode
Also when Evil Malamar are trying to take over the World Team Rocket helps Clemont gather the strength of wild Pokemon to defeat the Malamar
