About True Patience and Submission

Have got some beautiful words from one of my sis and pasting it here so they don't go lost:

Only the faithful understand the true nature of patience and live in the manner of which Allah approves, for they have accepted the Qur'an as their guide. And, only the Qur'an explains the real meaning of patience and the type of patience that is acceptable to Allah. For this reason, the only people capable of being "patient with a beautiful patience" are those who follow the Qur'an.
The source of their patience is their faith in Allah and their submission to Him. Like all of their other characteristics, patience emerges only through a true understanding of faith, because to believe is to understand that there is no deity but Allah, that He encompasses all things in His knowledge, that only Allah has the power to determine one's destiny, and that nobody can enjoy gain or suffer loss without His willing it.

One reason why the believers can show patience is because their faith enables them to appreciate Allah's might and glory. Those who know that Allah has boundless wisdom and boundless knowledge also know that only He can determine what will be the finest life for them.Thus, knowing that only Allah possesses this knowledge and wisdom, the believers put their trust in Him, fully aware that whatever He wills is always beneficial, even though the benefit may not be immediately apparent. Therefore, they display true patience. In other words, one characteristic of those who have true patience is that they are people who have grasped and embraced the nature of destiny.
