A call intercepted by Kyiv suggests that an estimated 25,900 civilians have been killed in Ukraine since the war started two months ago.
According to Ukrainian Communities and Territories Development Minister Oleksiy Chernyshov, 6,800 residential homes have also been destroyed as of April 2.
Sulaiman recently caught up with Vitali Klitschko - former heavyweight champion and now Major of Kyiv - and sent his full support to Klitschko and Ukraine.
He has now backed up his words by confirming that they are not only raising funds for the country but are also building a house for an 'influential' woman.
"Right now, we are trying to work hard to raise funds and raise awareness about Ukraine," Sulaiman told Planet Sport about their current project.
"The humanitarian aid is so much needed, the devastation is horrible. We live in a world that, what is used today, (and) tomorrow is forgotten.
"We are into the third month of a horrible war where many innocent people are dying, the effects worldwide are tremendous. The economies are hurt because so many products that have been limited from Ukraine and Russia."
"We are just hoping and praying that this ends soon. We are helping specific cases in Ukraine with donations. We are building a house for a beautiful woman who was very influential, a mother of many," said Sulaiman.
Other high-profile boxers past and present have also gone into battle to protect Ukraine, including heavyweight great Wladimir Klitschko - who continues to raise awareness on social media - as well as current champion Oleksandr Usyk and Vasyl Lomachenko.
While Usyk is now training for his upcoming rematch against Anthony Joshua in July, Lomachenko turned down the chance to fight for the lightweight titles to remain in his native.
