Musnad Ahmad 30:1450

'Abd al-Samad narrated to us, Hammam narrated to us, Qatadah narrated to us, from al-Nadr ibn Anas, from Bashir ibn Nahik, from Abu Hurayrah, that the Prophet, peace and blessings of Allah be upon him, said: "Whoever prays—meaning the morning prayer—one rak'ah, then the sun rises, let him pray another one to it." 'Affan narrated to us, Hammam narrated to us, he said: Muhammad ibn Jahadah narrated to us, Abu Hazim narrated to me, that Abu Hurayrah said: "The change in the breath of the fasting person is more pleasant—or he said: more beloved—to Allah than the scent of musk." He said: And I think he said: "From the right of the Throne, a caller calls out in the seventh heaven: 'Give the spender a replacement, and give—or hasten—for the withholding one destruction.'" He said: And Abu Hurayrah said: "The Messenger of Allah, peace and blessings of Allah be upon him, forbade the earnings of the cupper, and the earnings of the slave girl."
