Musnad Ahmad 30:3649

'Abd al-Malik ibn 'Amr and Surayj narrated to us, they said: Fulayh narrated to us, from 'Abd Allah ibn 'Abd al-Rahman—meaning Ibn Ma'mar Abu Tuwalah—from Sa'id ibn Yasar, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, who said: "Indeed, Allah, the Almighty and Majestic, says: 'Where are those who love one another for the sake of My Majesty? Today, I shall shade them in My shade, on a day when there is no shade except My shade.'"
