✦ A man sneezed beside Ibn Umar Radi allahu anhu and said: Al-Hamdulillah Wa As-Salamu Ala RasoolAllah. (All praise is due to Allah, and peace upon the Messenger of Allah)'. So Ibn 'Umar said: I can also say Al-Hamdulillah Wa As-Salamu Ala RasoolAllah. but this is not what the Messenger of Allah (ﷺ) taught us. He taught us to say: Al-Hamdulillah Ala Kulli Hal (or Alhamdulillah)."

Jamia Tirmizi,Book 41, Hadith 2738-Hasan

Sunan Ibn Majah, Vol 1, # 14-sahih

✦ It was narrated that Jabir bin Abdullah Radhi allahu anhu said:In his Khutbah the Messenger of Allah Sal-Allahu Alaihi Wasallam used to praise Allah as He deserves to be praised, then he would say: 'Whomsoever Allah subhanahu guides, none can lead him astray, and whomsoever Allah subhanahu sends astray, none can guide. The truest of word is the Book of Allah and best of guidance is the guidance of Muhammad Sal-Allahu Alaihi Wasallam . The worst of things are those that are newly invented (in religion) ; every newly-invented thing is an innovation and every innovation is going astray, and every going astray is in the Fire.
