Though the hashtag was first used in 2012, it didn't become popular until this Ramadan.
As it's Hassan's first vegan Ramadan, she documented her meals on social media, which has since drawn more attention to #VeganRamadan.
Hassan told BuzzFeed News she first tried being vegan around two years ago but it only lasted for six months.
She said she had to adjust and change the way she ate and try to eat healthier.
Hassan said she found being vegan to be more energising. "I wanted to be vegan because I ate plant-based [food] but I felt like it wasn't enough because I felt fatigue still.
"But going completely vegan gave me more energy and the drive to be productive throughout my day."
