Established Prophetic Sunnahs:
Approaching the prayer with tranquility and dignity.
On the authority of Abu Hurairah (may Allah be pleased with him), who said:
"I heard the Messenger of Allah (peace and blessings of Allah be upon him) say:
'When the prayer has started,
do not come to it running;
come to it walking,
and maintain your tranquility.
Whatever part of the prayer you catch, pray it,
and whatever you miss, complete it.'"
Agreed upon.
