Osborne, who had denied both charges, was sentenced at Woolwich Crown Court this morning.
Ali's daughter, spoke on behalf of his family after the sentencing.
Judge Bobbie Cheema-Grubb said Osborne's mind had been "poisoned" by far-right ideas as she sentenced the 48-year-old to life with no chance of parole for 43 years.
However, witnesses recalled Osborne saying: "I've done my job, you can kill me now" and "at least I had a proper go" to members of the public in the immediate aftermath of the attack.
Jurors took just under an hour to convict the "loner" father-of-four who carried out the attack "with a terrorist motive" after being radicalised by Far Right propaganda.
During the trial, jurors heard how Osborne had meant to attack a march celebrating "Jerusalem Day" earlier on June 18 but was unable to.
She said Osborne had become "obsessed" with Muslims in the weeks leading up to the incident after watching the BBC drama Three Girls, which was based on the true stories of victims of the Rochdale grooming gangs.
She said: "My son is always asking where his grandad is and why he can not go to the park every day to play with him any more". It was here where he felt most comfortable.

Riyad, after some time, can come back with us'. "I can understand disappointment, and it was a good opportunity for him". "He's going to go in the summer isn't he, I'm afraid, for Leicester supporters".
She said: "Our father, like the victims of most terrorism, was entirely innocent, which makes his death in this violent way all the more hurtful".
"We can not imagine the trauma he felt in his last few minutes".
Mrs Akhtar's son - Mr Ali's grandson - has also been affected since the attack.
He said: "In my civilian life I have lived overseas 90% of the time, mostly in Middle East, Arabic countries".
"This trial has been a horrendous ordeal for all those affected by the attack last June, particularly those called to give evidence in court, who had to come face to face with Osborne", said Dushal Mehta, a lawyer at Fieldfisher.
Osborne's trial heard how mobile phones and tablets found at his family home revealed multiple searches for English Defence League (EDL) founder Tommy Robinson and Britain First deputy leader Jayda Fransen.
Osborne, a "total loner", had become obsessed with Muslims after watching BBC drama Three Girls in May past year and was angered by what he deemed as inaction following a string of United Kingdom terror attacks, his estranged partner Sarah Andrews said.
