Prophet Mohammed's Birthday, an annual calendar event for Muslims, is more than just a celebration of his life, the Ahmadiyya Muslim Jama'at Fiji said.
A press release from the association said the occasion was an annual educational event for Muslims and non-Muslims alike.
"This is not an ordinary religious event. It is held to acquaint people with the Holy Prophet's grandeur and status," the Ahmadiyya Muslim Jama'at Fiji said.
And the Jalsa Sirat-un-Nabi - a gathering of people where discussions reflect on Prophet Mohammed's life, personality and precepts - held on Prophet Mohammed's Birthday, was a means of telling the world of his exemplary qualities that was God's gift to him.
"It is very unfortunate that a minority of the people whose hearts are perverted raise objections and false allegations to tarnish the honour of our master Holy prophet.
"This Jalsa will be a challenge to all those wrongdoers. We will tell them that we have stood up to suppress the evils of evildoers and to help the large number of well-mannered people so that peace may be established in the nation," the Ahmadiyya Muslim Jama'at Fiji said.
The association said it was futile to raise objections against the Muslim prophet as it would only intensify love for the founder of their religion.
"We will tell the world that their intention to separate the believers from Holy prophet will not happen, rather we will come even close to him," the association said.
The Ahmadiyya Muslim Jama'at Fiji urged Muslims and non-Muslims alike to participate in the Jalsa in a show of solidarity to "a great human being".
"There are many humble people in all religions. Their voices are suppressed by other people. It is our responsibility to take their suppressed voices and raise them to be heard by others.
"Through these gatherings, we give those people who are noble and are ready for harmony, the courage they need so that when they come forward, they can make a remarkable change in religions and among nations. "We will help them raise their voices so that mischief makers can be suppressed and well-mannered people will rise,' the association said.
The association said the Jalsa aimed to create tolerance, respect and courtesy in the nation.
"The teaching that we have been given is that we should be courteous and respectful towards holy men of all religions.
"All such men whom people regard as being sent by God must be given their due respect," the association said.
