The Israeli regime prime minister, Benjamin Netanyahu, has made the decision, according to the Israeli public broadcaster on Sunday.
Israel waged a genocidal military offensive on the Gaza Strip on Oct. 7.
More than 33,700 Palestinians, mostly women and children, have since been killed in Gaza, besides mass destruction and conditions of famine.
Claiming it to be “the last stronghold of Hamas,” Netanyahu has insisted on invading Rafah, where around 1.4 million displaced Palestinians have taken refuge from the incessant attacks.
Despite growing international outcry over the invasion plan, the prime minister last week said a date had been set for the offensive.
"Today I received a detailed report on the talks in Cairo, we are constantly working to achieve our goals, first and foremost the release of all our hostages and achieving a complete victory over Hamas," Netanyahu said.
"This victory requires entry into Rafah …. It will happen - there is a date."
According to the public broadcaster, the postponement of the ground operation came after consultations with the Israeli security apparatus.

Earlier on Sunday, finance minister Avigdor Smotrich called for invading Rafah and imposing control over the entire Gaza Strip.
The postponement comes after Iran's Islamic Revolution Guards Corps (IRGC) launched around 300 missiles and drones towards occupied territories late Saturday evening.
The unprecedented attack was in response to an April 1 missile attack targeting the consular section of the Iranian embassy in Damascus, which killed seven Iranian military advisors.
