Are you truly grateful?
“If you were to count Allah's favors, you would not be able to number them; most surely humanity is very unjust, very ungrateful.” [Sūrah Ibrāhīm: 34]
How often do you think about all the blessings Allah has bestowed upon you? The answer on this question is not that often, am I right? Instead, we more often think about things we don't have or want to have. And when we do think about these things, we get sad or bitter. "Why can he/she or them have that and not me, I deserve it more." Sounds familiar?
Instead of wasting precious time and giving the shaytan opportunity to misguide you, you should remember Allahs favors upon you and be grateful! You can be truly happy only when you appriciate Allah's gifts.
(a reminder to myself first and foremost)
Remember that Allah reminds us: “And whatever good thing you enjoy, it is from Allah. Then, when misfortune reaches you, you cry out to Him for help.” [Sūrah al-Nahl: 53]
