Two friends, Mohammed Hassan Ali bin Isa and Abdul-Jalil al-Arbash died after stopping the suicide bomber going into the mosque reports say.
Eyewitnesses claim that the suicide bomber was disguised as a woman with the intention of entering through the closed female entrance.
The authorities have warned females to keep away from mosques on Friday prayers because of fears of a repeat attack.
This comes one week after the deadly suicide bombing in Qatif that left 21 people dead.
2.7 million Shia live in Saudi Arabia making up 12 % of the population.
