Riyad as-Salihin 327
Heraclius asked me, "What does this Prophet (ﷺ) teach you?" I said, "He orders us to worship Allah Alone and not to associate a thing with Him in worship, to discard what our ancestors said, to perform the Salat (prayer), speak the truth, and maintain the ties of kinship". [Al-Bukhari and Muslim].
"اعبدوا الله وحده، ولا تشركوا به شيئًا، واتركوا ما يقول آباؤكم، ويأمرنا بالصلاة، والصدق، والعفاف، والصلة"
