Established Prophetic Sunnahs.
Glorification of Allah (tasbih).
On the authority of Juwayriyah (may Allah be pleased with her):
The Messenger of Allah (peace and blessings of Allah be upon him)
left her apartment early in the morning after performing the Dawn Prayer,
while she remained in her place of prayer.
He then returned at mid-morning and found her still sitting there.
He asked her,
"Have you remained in the same state in which I left you?"
She replied, "Yes."
The Prophet (peace and blessings of Allah be upon him) said,
"I recited four statements three times after I left you;
if they were to be weighed against all that you have recited today,
they would outweigh them:
'Glory be to Allah, and praise be to Him,
as many times as the number of His creation, as much as pleases Himself,
as heavy as the weight of His Throne,
and as vast as the ink of His words.'"
