grat·i·tude (grăt'ĭ-tūd', -tyūd')
The state of being grateful; thankfulness.
Abu Yahya Suhaib bin Sinan, may Allah be pleased with him, reported that Rasullulah (SAW) said:
“How wonderful is the case of a believer, there is good for him in everything and this applies only to a believer. If prosperity attends him, he expresses gratitude to Allah and that is good for him; and if adversity befalls him, he endures it patiently and that is better for him.” [Muslim]
