From the excellent words of Aaidh Qarni

عَسى تَأخيرك عَنْ سَفر خَيـر

 It is highly possible that you being delayed from a journey is better for you

...

و عَسى حِرمآنك مِنْ زَوآج "بَركة"
And it is highly possible that you being deprived of marriage is a blessing

و عَسى طّلآقّك منّ زوجك "راحة"
And its highly possible that your divorce from your spouse is ease

و عَسى رَدك عَن وَظيفة "مَصلحة"
And it is highly possible that you being refused a position is in your best interest

و عَسى تَأخرك و حِرمآنك مِنْ طِفل "خَير"
And it is highly possible that a delay in having a child or being deprived from one is for the best

{وَعَسَى أَنْ تَكْرَهُوا شَيْئًا وَهُوَ خَيْرٌ لَكُمْ وَعَسَى أَنْ تُحِبُّوا شَيْئًا وَهُوَ شَرٌّ لَكُمْ وَاللَّهُ يَعْلَمُ وَأَنْتُمْ لَا تَعْلَمُونَ.}
And it may be that you dislike a thing which is good for you and that you like a thing which is bad for you. Allah knows but you do not know(Aayah 216 Al Baqarah)

لأنّه يَعلمْ و أنت لا تَعلمْ ..
Because He knows and you do not know

فَلآ تتضآيق لأي شَيء يحدُث لك لأنه بإذن الله خَير ..
So do not be angry and annoyed for anything which happens to you because by the permission of Allah, it is best for you

 يُقآل ..
It is said

 لا تكثر من الشكوَى فَيأتِيك الهمّ ،
Do not complain excessively, as worries will come your way

ولكِـن ؛
But
آكْثِر من الحمدُلِلـَّه تأتيك آلسعَآدة "
Increase praising Allah, and good fortune will come your way♥
