Musnad Ahmad 624:12

Hassan ibn Musa narrated to us, Hammad ibn Zayd narrated to us, from Asim ibn Bahdalah, from Zirr ibn Hubaysh, who said: I came to Safwan ibn Assal al-Muradi, and he said: "What brought you?" I said: "Seeking knowledge." He said: "It has reached me that the angels surely lower their wings for the seeker of knowledge out of pleasure for what he does." Then he mentioned the hadith, and he said to him: The Messenger of Allah (ﷺ) said: "A person is with whom he loves." He said: He did not cease speaking to me until he told me: "That Allah, the Almighty and Majestic, has placed in the West a gate, the width of which is a journey of seventy years, for repentance; it will not be closed as long as the sun does not rise from its direction." And that is the saying of Allah, the Almighty and Majestic: {The day that some of the signs of your Lord will come, no soul will benefit from its faith} [Al-An'am: 158].
