from Nafi: "A man sneezed beside Ibn 'Umar and said: 'Al-Hamdulillah Was-Salamu 'Ala Rasulillah. (All praise is due to Allah, and peace upon the Messenger of Allah)'. So Ibn 'Umar said: 'I too say Al-Hamdulillah Was-Salamu 'Ala Rasulillah, but this is not what the Messenger of Allah ﷺ taught us. He taught us to say: "Al-Hamdulillah 'Ala Kulli Hal (All praise is due to Allah in every circumstance)."  

الْحَمْدُ لِلَّهِ وَالسَّلاَمُ عَلَى رَسُولِ اللَّهِ قَالَ ابْنُ عُمَرَ وَأَنَا أَقُولُ الْحَمْدُ لِلَّهِ وَالسَّلاَمُ عَلَى رَسُولِ اللَّهِ وَلَيْسَ هَكَذَا عَلَّمَنَا رَسُولُ اللَّهِ ﷺ عَلَّمَنَا أَنْ نَقُولَ الْحَمْدُ لِلَّهِ عَلَى كُلِّ حَالٍ
