The Most Patient, The Patiently-Enduring
The One who is most patient, steadfast, and enduring. The One who is not moved by haste to carry out any action before it's proper time.
The One who patiently endures and does everything in its proper time and proper manner, no matter how long that may take.
The One who patiently accomplishes each thing in its proper time, in the way
it needs to be and according to what it requires.
From the root s-b-r which has the following classical Arabic connotations:
The name Sabūr is not specifically used as a Beautiful Name in the Qur'ān.
Mankind's share of this attribute is the bountiful reward bestowed upon those who patiently persevere in overcoming the trials, lusts and errors of this world.
Sheikh Tosun Bayrak writes of al-Sabūr:
(Also written as al-sabur, al-saboor, as-sabur, as-saboor, the Most Patient: ya sabur, ya saboor)
