Heraclius said: "What does the Prophet enjoin you to do?" I said: "He tells us to worship Allah alone, not to associate anything with Him and to give up all that our ancestors said. He also commands us to perform prayers, adhere to truthfulness, be chaste, and maintain ties of kinship." [Al-Bukhari]
قال هِرَقل: فماذا يَأمُرُكُم -يعني: النبي صلى الله عليه وسلم- قال أبو سفيان: قلت: يقول: «اعبدُوا الله وَحدَه لاَ تُشرِكُوا بِهِ شَيئًا، وَاترُكُوا ما يَقُول آبَاؤُكُم، ويَأمُرُنَا بِالصَّلاَة، والصِّدق، والعَفَاف، والصِّلَة» رواه البخاري
