Well, in fanfiction, Naruto could save Arin's mom by using his signature jutsu. For example, if she was in danger from some powerful enemies, Naruto might use his Rasengan. He could quickly assess the situation, like finding out where the enemies are weakest, and then launch a surprise attack with his Rasengan to defeat them and save her.
Maybe Naruto saves Arin's mom through his ability to make friends and allies. He could convince some local villagers or other ninjas to help him. He'd use his charm and his story of growing up as an outcast but still achieving great things. They would then work together to rescue her from whatever peril she was in, like a hostage situation perhaps.
In fanfiction, Naruto might also save Arin's mom by using his Nine - Tails chakra. If she was trapped in a place full of dangerous traps or barriers, Naruto could tap into the Nine - Tails' power. This would give him extra strength and speed. He could break through the barriers and get to her in time, all while fending off any threats that come his way.
