Rescuer Mohd Zamri Abdul Ghani said Iman was spotted when he waved with a polystyrene board.
“We were really moved when we found him ... Because it’s already the fourth day” of the search mission, Zamri told journalists.
“He was excited to see us ... Physically, he looked exhausted.”
Iman was stranded near a waterfall, meaning he had a source of fresh water, the rescuer said.
Missing boat
Officials say the migrants on the capsized boat were members of the Rohingya community trying to reach Malaysia.
They were likely part of a larger group of some 300 people who had left Myanmar two weeks ago and were split between at least two boats.
Police reported the second vessel as missing and its fate was unknown.
As search operations continued, Malaysian authorities said another eight bodies had been recovered by Tuesday afternoon, taking the total to 20.
On the Thai side, an official told AFP on condition of anonymity that six bodies had been found, including at least two who carried identification cards issued by the United Nations’ refugee agency UNHCR.
Fourteen survivors, mainly Rohingya and Bangladeshi citizens, have been rescued in Malaysian waters since rescue operations started on Sunday.
At least 12 vessels were searching for survivors in an area of around 250 square nautical miles, roughly the same size as Singapore.
‘Urgent concerns’
Relatively affluent Malaysia is home to millions of migrants from poorer parts of Asia, many of them undocumented, working in industries including construction and agriculture.
Sea crossings, facilitated by human-trafficking syndicates, are hazardous and often lead to overloaded boats capsizing.
The Rohingya have been persecuted in Myanmar for decades, and thousands risk their lives every year to flee repression and civil war, often aboard makeshift boats.
In 2024, some 657 Rohingya died in the region’s waters, according to UNHCR figures.
Medical charity Doctors Without Borders (MSF) said that the latest shipwreck “raises urgent humanitarian concerns”.
“No one leaves Myanmar or Bangladesh by choice – these are dangerous boat journeys undertaken by people out of fear for their lives,” MSF said in a statement.
