Riyad as-Salihin, 327

Abu Sufyan Sakhr bin Harb (May Allah be pleased with him) mentioned Heraclius in a long Hadith and said:

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". <b>[Al-Bukhari and Muslim]</b>.

وعن أبي سفيان صخر بن حرب رضي الله عنه في حديثه الطويل في قصة هرقل أن هرقل قال لأبي سفيان‏:‏ فماذا يأمركم به‏؟‏ يعني النبي صلى الله عليه وسلم قال‏:‏ قلت‏:‏ يقول‏:‏ ‏

‏اعبدوا الله وحده، ولا تشركوا به شيئًا، واتركوا ما يقول آباؤكم، ويأمرنا بالصلاة، والصدق، والعفاف، والصلة‏

‏ ‏(‏‏(‏متفق عليه‏)‏‏)‏‏.‏

<b>Guidance from the Hadith:</b><br> 1) The mission of the Prophet (may Allah’s peace and blessings be upon him) was founded on worshiping Allah Almighty in a good manner by proclaiming His oneness, and being kind to the people by maintaining ties with them and fulfilling their rights.<br> 2) The command to uphold ties of kinship is one of the first provisions laid down by Islam, the thing that testifies well to its significance.
