Friday is a very significant day for Muslims. Rather than being alone, Friday prayer is in congregation meaning mosques are typically full of worshippers.
"This was a targeted attack, so we are afraid for our students. We're afraid for our children, but we also want to urge the community to not lose hope. Pray today," said Sobia Siddiqui with CAIR Houston.
Houston police told ABC13 overnight they have "an increased awareness of the mosques" in the area in light of this attack.
This is not the first time this year authorities have beefed up security at area mosques.
Back in January, bullets went flying at the Muslim American Society-Katy Center (MAS) Mosque.

Fortunately, no one was hurt.
One bullet hit the building. Another left a hole in the windshield of one of the cars in the parking lot.
The center worked to increase patrols after the incident.
At the time, representatives of the mosque said they were ready to welcome the person responsible.
"We will forgive him. We'd love to work with him for him to have the right information as a community here in America," Hesham Ebaid, vice president of the center, said in January.
