Musnad Ahmad 30:991

Yahya ibn Adam narrated to us, Ibn al-Mubarak narrated to us, from Ma'mar, from Hammam ibn Munabbih, from Abu Hurayrah, from the Prophet, peace and blessings of Allah be upon him, regarding the saying of the Almighty, the Majestic: "Enter the gate prostrating" [An-Nisa: 154]. He said: "They entered crawling." And regarding "And say, 'Hittah' (relieve us of our burdens)" [Al-Baqarah: 58], he said: "They altered it, so they said: 'Hintah' (a grain of wheat) in a hair."
