A Sudanese official had said that Meriam Ibrahim, who gave birth to a daughter in custody, would be freed in a few days.
But Daniel Wani said no one had contacted him about his wife’s release.
He said he had only heard media reports, which he described as rumors.
“No Sudanese or foreign mediator contacted me. Maybe there are contacts between the Sudanese government and foreign sides that I’m not aware of,” Wani told Mohammad Osman, the BBC’s correspondent in the Sudanese capital Khartoum.
“As far as I’m concerned I will wait for the appeal, which my lawyer submitted, and I hope that my wife will be released.”
Abdullahi Alzareg, an undersecretary at the foreign ministry, said Saturday that Ibrahim, 27, would be freed because Sudan guaranteed religious freedom and was committed to protecting her.
Ibrahim was brought up as an Orthodox Christian, but a judge ruled last month that she should be regarded as Muslim because that had been her father’s faith.
She refused to renounce her Christianity and was sentenced to death by hanging for apostasy.
