What to say when something that pleases you happens
The dua in its Arabic wording from Hisn al-Muslim, with its English meaning.
بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
Bismillahir-rahmanir-raheem
Each dua: the Arabic, then a transliteration to help you say it aloud, then its meaning.
((كَانَ النَّبيُّ صلى الله عليه وسلم إِذَا أَتَاهُ أَمْرٌ يَسُرُّهُ أَوْ يُسَرُّ بِهِ خَرَّ سَاجِداً شُكْراً لِلَّهِ تَبَارَكَ وَتَعَالَى)).
Kanan-nabiyyu sallallahu 'alayhi wasallama idha atahu amrun yasurruhu aw yusarru bihi kharra sajidan shukran lillahi tabaraka wata'ala
(The Prophet PBUH would prostrate in gratitude to Allah upon receiving news which pleased him or which caused pleasure. )
