Hadith 8:2499
Abu Bakr narrated to us, he said: Waki’ narrated to us, from al-Busayr ibn ‘Adi, from Ibn Abi Husayn, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The greatest of my supplication and the supplication of the prophets before me on the Day of Arafah is: 'There is no god but Allah alone, He has no partner. To Him belongs the dominion, and to Him belongs the praise. In His hand is all good, He gives life and causes death, and He is capable of all things.'"
حدثنا أبو بكر قال حدثنا وكيع عن البصير بن عدي عن بن أبي حسين قال قال رسول الله صلى الله عليه وسلم اكبر دعائي ودعاء الأنبياء قبلي بعرفة لا إله إلا الله وحده لا شريك له له الملك وله الحمد بيده الخير يحيى ويميت وهو على كل شيء قدير
