Abu Hurairah (Allah be pleased with him) reported that Prophet (peace be upon him) said “Never a believer is stricken with a discomfort, an illness, an anxiety, a grief or mental worry or even the pricking of a thorn but Allah will expiate his sins on account of his patience”. [Source Al-Bukhari Book 32 H # 6243]

“Patience does not mean to passively endure. It means to be farsighted enough to trust the result of a process… What does patience mean? It means to Look at the Thorn and see the Rose, to look at the Night and see the Dawn.
Impatience means to be shortsighted as to not be able to see the outcome. The lovers of God never run out of Patience, for they know that Time is needed for the Crescent Moon to become Full.” {Subhan Allah}

Thankfulness and Patience
“Whatever happens in your life, no matter how troubling things might seem, do not enter the neighborhood of Despair. Even when all doors remained closed, ALLAH will open up a new path only for you. Be Thankful! It is easy to be thankful when all is well. But be thankful not only for what you have been given but also for all that you have been denied.
