CNBC's Jim Cramer fired back on critics Monday who claimed that Apple's iPhone 7 sales wouldn't be as good, if Samsung didn't have its Galaxy Note 7 recall.

"I saw some pieces this weekend ... these are the greatest ones. 'If the Samsung phone didn't catch fire, then Apple wouldn't do that well,'" Cramer said on "Squawk on the Street." "Oh, okay. Well, yeah, sure if it didn't."

Last week, the U.S. Consumer Product Safety Commission officially recalled Samsung's premium device, urging all consumers to take advantage of the recall immediately. On Monday, reports said that two Note 7 smartphones had caught fire in China.

Meanwhile, Apple said last week that its initial quantities of the iPhone 7 Plus sold out globally.

Cramer added, "If [Samsung] got the phone working, it would really be a challenge to Apple."

Separately, JPMorgan analyst Rod Hall said Monday that Apple's recent rally is "premature" as unsustainable promotions are boosting demand.

Apple's stock was trading at slightly higher at $115.40 a share mid-morning Monday. The stock is up more than 9 percent year to date.
