Abu al-Muntafiq said: I came to Makkah and asked about the Messenger of Allah (peace and blessings be upon him), and the people said: (He (peace and blessings be upon him) is) at Arafah. So I came to him (peace and blessings be upon him) and began drawing near until the neck of my mount went past the neck of his (peace and blessings be upon him) mount, and I said: O Messenger of Allah! Teach me what will save me from the punishment of Allah and admit me into His Paradise. He (peace and blessings be upon him) said: "Worship Allah and do not associate anything with Him, establish the obligatory prayer, pay the obligatory zakah, and perform Hajj and Umrah," and I think he (peace and blessings be upon him) also said: "Fast Ramadan, and see what you would love people to do to you and do it to them, and what you dislike them doing to you, leave them alone from it." Al-Tabarani (may Allah have mercy on him) said: Ibn Awn became confused in the chain of this hadith and did not preserve it accurately from Muhammad bin Juhadah, whereas Hammam preserved it accurately.
