Thousands of mourners joined the family of Muhammad Ali to pay their respects to the sporting legend in a moving prayer service. Over 14,000 people traveled from all over the world to attend the traditional Muslim prayer service or Jenazah at the Freedom Hall on Thursday 9 June in his hometown of Louisville, Kentucky.

The prayer service marks two days of memorials in honour of the sports star and was attended by family members such as his wife, Lonnie, who was accompanied by daughters, Laila and Hana, and Ali's granddaughter Sydney.

"We welcome all of you here today. We welcome the Muslims, we welcome the members of other faith communities, we welcome the law enforcement community. We welcome our sisters, our elders, our youngsters. All were beloved to Muhammad Ali," he said.

Offering an insight into Ali's global influence, he said that: "One reason Muhammad Ali touched so many hearts, he was willing to sacrifice the fame, the lights, the money, the glamour, all of that, for his beliefs and his principles," Imam Shakir said. "That's moving and that touches people."

The 20- minute service which marks the start of two days of memorial events, comprised of four recitations of 'Allahu Akbar' or 'God is Great,' with silent prayers in between of a reading from the first chapter of the Quran. There was also a blessing for Abraham and prayers both for Ali and for funeral attendees, Mail Online reported.

Sherman Jackson, a prominent member of the Muslim-American community, offered condolences hailing Ali as "an unapologetic fighter in the cause of black people in America — and not just the classes among black folks, but even more especially the masses.

"Ali was the people's champion, and champion he did the cause of his people," Jackson added.

They will see the true nature of the religion and the way that Muslims - the majority of Muslims - live."
