The word(s) "foot" appears 23 time(s) in 22 verse(s) in Quran in Muhammad Pickthal translation.

(21) These it was who disbelieved and debarred you from the Inviolable Place of Worship, and debarred the offering from reaching its goal. And if it had not been for believing men and believing women, whom ye know not - lest ye should tread them under foot and thus incur guilt for them unknowingly; that Allah might bring into His mercy whom He will - If (the believers and the disbelievers) had been clearly separated We verily had punished those of them who disbelieved with painful punishment.

(22) Then We caused Our messengers to follow in their footsteps; and We caused Jesus, son of Mary, to follow, and gave him the Gospel, and placed compassion and mercy in the hearts of those who followed him. But monasticism they invented - We ordained it not for them - only seeking Allah's pleasure, and they observed it not with right observance. So We give those of them who believe their reward, but many of them are evil-livers.
