The flogging of writer Raif Badawi has been postponed by Saudia officials on medical ground, Amnesty International has said.
Mr Badawi, who was flogged 50 times in public a week ago by an Interior Ministry official, was due to face the same punishment every Friday until he had received 1,000 lashes, followed by 10 years in prison.
Amnesty International said the prison doctor concluded that the wounds Mr Badawi had received from his previous beating had not yet healed properly and that he would not be able to withstand another round of lashes at that time.
Following news of the postponement, Amnesty International's Deputy Director for the Middle East and North Africa Programme said: "Not only does this postponement on health grounds expose the utter brutality of this punishment, it underlines its outrageous inhumanity.
"The notion that Raif Badawi must be allowed to heal so that he can suffer this cruel punishment again and again is macabre and outrageous."
Saudi Arabia has come under increased pressure from Western countries over its weekly flogging of Mr Badawi for "insulting Islam", particularly since the Paris attack on Charlie Hebdo magazine, which was condemned by Riyadh.
The UN human rights chief this week urged the Saudi king to pardon Mr Badawi and review the "cruel" penalty of flogging.
"Flogging is, in my view, at the very least, a form of cruel and inhuman punishment," UN commissioner Zeid Ra'ad Al Hussein said in a statement.
The United States, Amnesty International and Reporters Without Borders all denounced the flogging as a horrific form of punishment, saying Mr Badawi was exercising his right to freedom of expression.
His wife Ensaf Haidar, who sought asylum in Canada with their three children after Mr Badawi was jailed in June 2012, has also pleaded for his release
The co-founder of the now-banned Saudi Liberal Network was found guilty of insulting Islam after criticising Saudi Arabian clerics on a forum he founded in 2008.
In the past year Saudi authorities have been criticised by international rights groups for jailing several prominent activists on charges ranging from setting up an illegal organisation to damaging the reputation of the country.
However, the country is reluctant to be seen to yield to Western pressure with large numbers of conservative Saudis defending the punishment on social media, and accusing the authorities of being weak in the face of insults to Islam in the West - particularly the publication of cartoons of the Prophet Mohammed in publications such as Charlie Hebdo.
