SIRAH: There are some among you who scare people away...

Mu'adh ibn Jabal (RA) was one of Rasulullah's (SAW) closest and
learned companion. He was an Imam (Leader of the Prayer) in a
neighborhood of Madinah. In the prayer of Fajr he used to recite long
verses of the Qur'an. Someone came to Rasulullah (SAW) and said,
"O Rasulullah, Mu'adh recites long chapters of the Qur'an. His
prayers are so long that I get tired. I prefer not to offer prayer with
jama'ah (congregation in the masjid)." Rasulullah (SAW) heard this
and became concerned.

Rasulullah (SAW) addressed the people and said, "There are some
among you who scare people away. Whoever leads the salat (prayer)
among you, should recite short portions of the Qur'an because there
are the weak and the aged and those who have bussiness to attend.
Show them special concern."
