Mr Jahan was honoured for his compassion in the aftermath of his son's death
A father who appealed for calm during the Birmingham riots accused a man of staring at his wife before punching him to the ground, a court has heard.
Tariq Jahan, 46, assaulted Sajjad Ali after an argument outside Mr Ali's workplace in Handsworth on 6 July last year, Birmingham Crown Court was told.
Mr Ali, 33, told jurors Mr Jahan accused him of "staring at my missus".
Mr Jahan, 46, from Winson Green, Birmingham, denies causing grievous bodily harm with intent.
Mr Ali told the court Mr Jahan had driven up to him in his car and said: "Oi, why you staring at me?" before getting out and then accusing him of "staring at my missus".
He told the jury that he was grabbed by the throat by the defendant, punched in the face and knocked to the floor, then kicked or punched while he was on the ground.
Fractures to jaw
Mr Ali told the jury of five women and seven men that Jahan's manner was "really aggressive" when he approached him and accused him of staring.
He said he thought the attack lasted five minutes or less but he did not know if a number of blows he received while he was on the floor were kicks or punches and said: "It was just bang, bang, bang on my head."
Mr Ali was taken to hospital by his manager and treated for two fractures to his jaw and also lost two teeth.
Mr Jahan denies one count of causing grievous bodily harm with intent and inflicting grievous bodily harm.
'Self defence'
Prosecutor Shenaz Muzaffer told the court a medical expert concluded a "moderate to severe" use of force would have been required to cause the injuries to the jaw.
She added: "The defendant does accept that he did have an altercation with Mr Ali but says he was acting in self defence."
Ali Naseem Bajwa, QC, defending Jahan, suggested to Mr Ali that he had been the aggressor in the incident after he became annoyed that Jahan was beeping his car horn to get him to move.
Mr Ali said "that's not true" when Mr Bajwa suggested he had "mouthed words" in the defendant's direction as he drove past.
Mr Jahan stopped his car and asked him if he was a Hindu, Pakistani, Sikh, Muslim or Iraqi and said a few words to him in Punjabi, Mr Bajwa told the court.
Mr Bajwa said the pair got into a scuffle before Mr Ali was punched once to the side of the jaw, which caused him to fall to his knees.
Mr Jahan won widespread praise just over a month after the alleged attack when he made an emotional appeal for peace in the hours following the death of his 21-year-old son Haroon in Birmingham in August 2011.
Call for calm
Haroon Jahan and brothers Shazad Ali, 30, and Abdul Musavir, 31, were struck by a car in the early hours of August 10 during disorder in Winson Green.
They were pronounced dead in hospital and hailed as heroes who died protecting homes and shops from looters.
Mr Jahan, of Winson Street, Winson Green, made a heartfelt plea to crowds of youths gathered outside his home to end the disorder and "go home".
His personal call for calm was credited with helping to prevent the riots from escalating.
He received a Pride of Britain special recognition award for his compassion and dignity in the aftermath of his son's death.
The trial continues.
