Musnad Ahmad

Ziyad bin Abi Ziyad (may Allah have mercy on him) says that once, after Umar and I had finished offering the Zuhr prayer—which was led by Hisham bin Isma'il, as he was the governor of Madinah at that time—we went to inquire about the health of Amr bin Abdullah. We did not sit there; we only asked about his condition while standing. Then we went to visit Anas (may Allah be pleased with him), whose house was next to the house of Abu Talhah (may Allah be pleased with him). As soon as we sat down there, a slave girl came to him and said, "O Abu Hamzah! The time for prayer has come." We asked, "May Allah's mercy be upon you, which prayer?" He replied, "The Asr prayer." We said, "We have just offered the Zuhr prayer." He said, "You have neglected the prayer to the extent that you have forgotten it. I heard the Prophet (peace and blessings of Allah be upon him) say: 'I and the Hour have been sent like these two fingers together.'" Saying this, he pointed with his index and middle fingers and extended them. Hadith number (13509) is also narrated through this second chain.
