The Pars host the Light Blues hoping to become the first side to beat the high-flying Ibrox side in the league this season.
Husband insists the Fifers will approach the live TV encounter with confidence, despite losing 3-1 the last time the teams faced each other in Govan back in November.
On that occasion the scores were still level until the 71st minute when Lee McCulloch won Rangers a controversial penalty that also resulted in Dunfermline's on-loan Dundee United striker Jordan Moore being sent off.
But, with that defeat remaining the Pars' only setback in their last 11 matches, Husband hopes the five-point advantage they go into the match enjoying over third-placed Stranraer means they can go out to attack Rangers.
The 23-year-old former Hearts and Blackpool midfielder said: "With the gap we've got we've given ourselves a bit of room to play with. That's what the gaffer wanted, so we can go and have a go at Rangers.
"Rangers have not been beaten yet and that is an incentive for every team to be the first. Stranraer did fantastic to draw - Ally (McCoist) said that they deserved it - but nobody has beaten them in the league."
