He joined to Al Qassam brigades in the first intifada in 1987. the brigades leadership saw his courage and his commitment so they agreed to let him a member in the Brigades. He participated in defending many areas in Rafah as "Al Salam", "Brazil" neighborhoods, and the east side of Rafah. He was the friend of the martyrs "Ayed Al Bashity" and "Yousif Al Mallahi".

He also was watching the Zionist vehicles near Al Salam neighborhood. He shared in digging a tunnel for Rafah cross. His friends said that he was always ready for any an emergency situation. They added "he was a leader".
Interested actions in his life
He was guarding his neighborhood. Suddenly, a man come and started to shout on him. And pronounced with bad words towards Mosa. But Mosa didn’t become nervous. He talked to him quietly. The man understood why Mosa and his friends stood in that position.
Before Martyrdom
Before a day of his martyrdom, he came back to house and found that his children playing with the family pictures. He stand and said" don’t play with it, you will need it ". He told his elder son "keep the land, even if the Zionist army destroyed the house". He said to his wife " today is the last day" as he was knowing that he is going to be a martyr.
The martyrdom day
Mosa went to execute a mission against Zionist tank. He went with two of his friends to shell RBG rocket toward the tank. The rocket wrongly exploded and caused his martyrdom .
I'm only disappointed that they didn't provide the date that he met with his virgins so I could verify that I had counted him as one of the PalArab self-deaths.
