Narrated Abu Huraira:

The Prophet (ﷺ) said, "It was said to the children of Israel, 'Enter the gate (of the town), prostrate (in humility) and say: Hittatun (i.e. repentance) i.e. O Allah! Forgive our sins.' But they entered by dragging themselves on their buttocks, so they did something different (from what they had been ordered to do) and said, 'Hittatun,' but added, "A grain in a hair."

Narrated Abu Huraira:

Allah's Messenger (ﷺ) said, "It was said to the children of Israel, 'Enter the gate in prostration and say Hitatun. (7.161) We shall forgive you, your faults.' But they changed (Allah's Order) and entered, dragging themselves on their buttocks and said, 'Habatun (a grain) in a Sha'ratin (hair).
