Grace Wheeler's daughter Karleena was diagnosed with paranoid schizophrenia 3 years ago and became ill on holiday.
He appeared at Sheffield Crown Court today to be sentenced and was jailed for life, to serve a minimum of 23 years.
Police were called to Manaa’s home address on The Oval in Firth Park at around 2.15pm on Tuesday, 4 March, 2014, after reports had been received that he had killed his wife.
On arrival, the body of Miss Shourefi was found in a cupboard under the stairs.
A post-mortem examination concluded she died as a direct consequence of her injuries, which consisted of multiple stab wounds and blunt force trauma to her head and body.
Manaa was arrested at the scene and charged with murder on Thursday, 6 March.
DCI Zaf Ali, the Senior Investigating Officer leading the case said:
'My thoughts and condolences are with Sara’s sister and extended family at this time, and I hope they have some form of closure after today.
'This was a vicious attack on a woman that has left four young children without their mother and a family completely destroyed.
'Sara was kept isolated by Manaa and suffered serious domestic abuse at his hands in silence, believing it was not culturally right to speak to the police or medical professionals against her husband.
'Regardless of background, culture or religion, I would strongly encourage any woman or man, to please report any form of domestic abuse; it is a crime that should not just be accepted as the ‘norm’ and the victims should not have to suffer in silence.”
Sara’s family do not wish to speak of their loss and have asked the media to please respect their privacy.
