106. What to say upon receiving pleasing or displeasing news

كَانَ النَّبِيُّ صلى الله عليه وسلم إِذَا أَتَاهُ الْأَمْرُ يَسُرُّهُ قَالَ: (الْحَمْدُ لِلَّهِ الَّذِي بِنِعْمَتِهِ تَتِمُّ الصَّالِحَاتُ) وَإِذَا أَتَاهُ الْأَمْرُ يَكْرَهُهُ قَالَ: (الْحَمْدُ لِلَّهِ عَلَى كُلِّ حَالٍ)

When something happened that pleased him, the Prophet (ﷺ) used to say: Praise is to Allah Who by His blessings all good things are perfected. And if something happened that displeased him, he used to say: Praise is to Allah in all circumstances.
