Etiquette of Greeting When Entering the Masjid

Shaykh al-Albaanee (rahimahu`Allah) said:

"When one comes into the Masjid and is about to greet, he greets so low so that only those around him hear. He shouldn't greet with a loud voice so that he disturbs the others in the Masjid."

(Silsila al-Huda wan Noor, 177)
