Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) says: (a) "Do not form rows between the pillars, and do not pray while there are people in front of you who are wrangling or playing."
(b) This mawquf report concerns people wrangling in front of him, so that the sound of their voices and their talk takes away the humility (khushu') of the prayer; so he should avoid them as much as he can. But if someone is sleeping in front of him, there is no harm in it; the Prophet (peace and blessings be upon him) used to do this.
