Relations between the two countries have deteriorated following the Egyptian military's overthrow of president Mohamed Morsi and a deadly crackdown on his Muslim Brotherhood movement, which Qatar backs.
The Qatari Al-Jazeera news broadcaster has also incensed Egypt's government with its coverage of a police crackdown on persistent Brotherhood protests since Morsi's overthrow in July.
"The Qatari ambassador was summoned over a statement by the Qatari foreign ministry," Egyptian foreign ministry spokesman Badr Abdelatty told AFP.
