A woman who beat her son to death for failing to learn parts of the Koran has been jailed for life, with an order to serve a minimum of 17 years.
Sara Ege's seven-year-old son Yaseen died in July 2010 from internal injuries after months of punishing beatings. She then set fire to his body to hide the evidence.
His death was treated as a terrible tragedy in the aftermath of the blaze but it was quickly found he was dead before the fire began.
The court heard how Yaseen was beaten often with a wooden pestle after failing in his Koran studies.
Trial judge Mr Justice Wyn Williams accepted that in some areas she was a "good mother" and had suffered prolonged bouts of depression due to a number of factors.
However he added: "His injuries must have caused him a good deal of pain. In my judgment Yaseen was subjected to prolonged cruelty."
Ege accused her husband Yousef of being a violent bully who beat her and was their son's real killer.
But he was cleared of causing or allowing his son's death at home in Pontcanna, Cardiff, south Wales, by failing to act to prevent it.
Ege, dressed in brown, with a matching headscarf, sobbed throughout the one-hour hearing on Monday.
She had to be helped, trembling and sobbing, from the dock.
The judge went on to highlight the crucial last three months of Yaseen's life.
"The violence that you perpetrated on your son was not confined to one day," the judge told Ege as he passed sentence.
"There is a further aggravating feature and that is that you attempted to burn Yaseen's body. There can be no doubt that you set fire to his body in an attempt to evade the consequences of what you had done."
He added: "What was your motive for acting as you did? I am satisfied that, on the day of his death, Yaseen was kept home from school so that he could dedicate himself to his (Koran) studies.
"On that day Yaseen must have failed in some way because I am satisfied that it was that failure which was the trigger for the beating.
"That is what you told the police in the course of your confession in July 2010 and I see no reason to doubt what you then said was true."
