كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا أَتَاهُ الْأَمْرُ يَسُرُّهُ قَالَ: الْحَمْدُ لِلَّهِ الَّذِي بِنِعْمَتِهِ تَتِمُّ الصَّالِحَاتُ ، وَإِذَا أَتَاهُ الْأَمْرُ يَكْرَهُهُ قَالَ: الْحَمْدُ لِلَّهِ عَلَى كُلِّ حَالٍ ⁽¹⁾.

When he (Peace Be Upon Him) used to receive pleasant news, he (Peace Be Upon Him) would say: Alhamdu lillahil-lathee biniAAmatihi tatimmus-salihat.
‘All Praise is for Allah by whose favour good works are accomplished.’ …and upon receiving displeasing news, he (Peace Be Upon Him) would say: Alhamdu lillahi AAala kulli hal. ‘All Praise is for Allah in all circumstances.
