Talking to media in Islamabad, he said the world court has, by way of provision measures, has asked to maintain status quo in the case of Indian spy, who is involved in fanning terrorism in Pakistan.
Jadhav was arrested in the southwestern Pakistani province of Balochistan in March 2016.
United Nations court orders Pakistan to stay the execution of Jadhav, a retired Indian naval officer, in a setback to Islamabad. He added that the ICJ verdict had shown that the military court trial by Pakistan was a "charade", and that the neighbour had been completely "blown away" by it.
India had moved the UN's highest judicial body against the death sentence to Jadhav after Pakistan ignored its request for consular access to the former navyman 16 times.
Global law expert Ahmer Bilal Soofi was of the view that Pakistan should prepare for the second phase of this case, which was more important because it would be contested on merit and would provide Pakistan the chance to document India's intervention inside Pakistan through Jadhav.
But India has maintained he is not a spy, and has accused Pakistan of violating the Vienna Convention by failing to provide him with consular access, as well as breaking worldwide human rights law.
This is a big diplomatic win for India.
CPI (M) general secretary Sitaram Yechury, now in Hyderabad, though noted the ICJ has reiterated its earlier position that Pakistan should wait till the time the worldwide court disposes of the case.
External Affairs Minister Sushma Swaraj welcomed the ruling. Giving his reaction, Union home minister Rajnath Singh said: "The ICJ's decision to stay the execution of Kulbhushan Jadhav gives the people of India a deep sense of satisfaction and relief", Singh said in a statement.
Meanwhile, Pakistan adviser on foreign affairs, Sartaj Aziz said Islamabad would decide about the consular access to Jadhav in the light of "national security dynamics".
"Unless a person has access to his own consulate he can't even get a counsel of his own choice".
Pakistan's Foreign Office said it did not accept the ICJ's jurisdiction in matters related to national security.
Marriyum Aurangzeb said any reporting on the interim order of International Court of Justice (ICJ) on Kulbhushan Jhadav case should be done responsibly. "We were very surprised how swiftly Jadhav's case was fixed before the ICJ", he said.
The court's decision came on a day when the party and the government were grieving because of the suddening death of environment minister Anil Dave.
Pakistan's attorney general's office said the order did not affect the final outcome of the case.
In the two-page order, Justice Abraham also dismissed Pakistan's contention that the court had no jurisdiction over the case.
Judge Abraham stated that the ICJ had prima facie jurisdiction under Article 1 of the Optional Protocol to the Vienna Convention.
