Sayyiduna Anas reports that Rasulullah (peace and blessings be upon him) once passed by a Bedouin who was making the following du'aa in his Salaah:

"O The One Whom eyes cannot see,
Who cannot be imagined,
Who is beyond description,
Who is unaffected by happenings,
Who cannot be overwhelmed by the vicissitudes of time,
Who knows the weight of the mountains,
the volume of the oceans,
the number of falling raindrops,
the number of leaves on the trees and everything upon which the night darkens and upon which the day brightens.
No sky can hide another from Him,
no surface of the earth can hide another from Him,
no ocean can hide anything within its depths from Him and
no mountain can conceal from Him anything within its rocks.
Make the last part of my life the best, make the best of my deeds the last
and make my best day be the one in which I meet You."

Rasulullah (peace and blessings be upon him) appointed someone to bring the Bedouin to him as soon as he completed his Salah.

Rasulullah (peace and blessings be upon him) had been given some gold from a certain mine and when the Bedouin came before him after he had completed his Salah, Rasulullah (peace and blessings be upon him) handed over the gold to him saying,

"Which tribe do you belong to, dear Bedouin?"

When the Bedouin informed Rasulullah (peace and blessings be upon him) that he belonged to the Banu Aamir bin Sa'sa'ah tribe,

Rasulullah (peace and blessings be upon him) asked,
"Do you know why I gave you this gold as a gift?"
"Because of the family ties between us, O Rasulullah (peace and blessings be upon him)," the Bedouin surmised.

Rasulullah (peace and blessings be upon him) said,
"While family ties have a right, I actually gave you the gold because of the beautiful manner in which you praise Allah."
