A few minutes after his first message, he said: "How can I be disappointed with someone ended their own life? If anyone can do that to themself (sic), they can do worse things to others."
After writing that message, he followed it with yet another cryptic post, that said:
"Your power proved to me you could make a town not react to loud noise at odd hours. Your power proved to me you could turn friends, family and strangers into liars, cowards and very much inhuman and yet this mega power can't make or keep someone kind or loving. And I cannot wait to prove that to you. With all my hate."
It seems as if the hairdresser wrote all of the messages himself, although he told fans on July 31 that his email had been hacked.
The Twitter tirade comes after Andros Georgiou, George Michael's cousin, revealed to the Sun that Fadi didn't get anything in the singer's will.
Instead, the late singer's money was left to charities, his sisters and some of his staff.
Mr Georgiou said Fadiwas contesting his exclusion from the will.
He said: "Fadi is threatening to go all the way to High Court but I think the estate will have to settle with him. He's been offered £500,000 and I think the estate should pay a couple of million to get rid of him."
On July 21, Fadi claimed George committed suicide on Christmas Eve following four previous attempts to take his own life.
Fadi said the Wham! pop star took his own life in 2016 and lay dead for 24 hours before he was found.
Writing in a series of emails, Fadi said: "It took five attempts... I'm sick and tired of people asking me what happened on Christmas Day."
Fadi said that the death on Christmas Eve coincided with George's beloved late mother's birthday.
The emails, seen by The Sun, continued: "Let me tell you, George died on his mother's birthday, so that might answer a few questions.Not to mention it took five attempts to manage to end his life. I think it's important for the story."
