His wife and children died next to him in the rubble, where he was trapped for nearly three days.
They'd fled war in Syria.
Lying in bed, having also lost a leg, Muaini remembers the home they'd made together in Hatay, southern Turkey.
For about 12 hours Muaini was able to talk to his wife Esra, their 10-year-old son Muhsin and daughter Basira, aged 7, before he lost them.
"May God have mercy on them, my wife and children are gone. My brother Abdul Rahim, may God have mercy on him, and my brother-in-law also passed away, may God have mercy on him. I lost these people, and we were one family together. We would go from our work to our home and from our home to our work, we would go to visit each other, have fun. All of that is gone, praise be to God."
The magnitude 7.8 tremor levelled towns and swathes of cities in the southeast and in neighbouring Syria.
It killed more than 50,000 people in Turkey and 5,900 in Syria, and left millions homeless.
Hatay was the hardest-hit province.
One of Muaini's legs was amputated and the other was paralysed below the knee from the crush of concrete and brick.
Muaini moved to Bursa in the northwest where he lives with his mother, sister and her three children. They keep him going.
"Praise be to God, I am sitting here and reading a little of the Koran, reciting rosaries, praying, having fun with my family, with my mother, my sister, my brother's children, and my sister's children. This is how my day passes."
Muaini recently started physiotherapy, and dreams of getting a prosthetic leg so he can get back to work, pay off bills and maybe one day return to his homeland.
In Bursa, rent is five times higher than in Hatay, and Muaini says he relies on his brother for that and food.
Medical bills are also piling up.
"There are no plans, but if I have the leg fitted, there is work I can do. Whatever it is, the individual must work, devote his time and thought, and help himself with his expenses and other things."
Muaini fled war in northwest Syria in 2016 with his wife and son, and sold fruit and vegetables for a living.
Turkey has accepted millions of Syrian refugees from the nearly 13-year war.
