Musnad Ahmad 201:3

'Abd al-Razzaq narrated to us, he said: Ma'mar narrated to us, from Abu Ishaq, from al-Mughirah, from his father, who said: I reached a man who was speaking to some people, so I sat down. He said: The Messenger of Allah (peace and blessings of Allah be upon him) described [something] to me while I was at Mina, setting out for 'Arafat—then he mentioned the hadith—and I said: "O Messenger of Allah, inform me of a deed that will bring me closer to Paradise and distance me from the Fire." He said: "Establish the prayer, give the zakat, perform the pilgrimage to the House, fast Ramadan, love for the people what you love to be brought to you, and dislike for them what you dislike to be brought to you. Clear the way for the riders."
