The word(s) "well-nigh" appears 2 time(s) in 2 verse(s) in Quran in Muhammad Habib Shakir translation.

(1) And when Musa returned to his people, wrathful (and) in violent grief, he said: Evil is it that you have done after me; did you turn away from the bidding of your Lord? And he threw down the tablets and seized his brother by the head, dragging him towards him. He said: Son of my mother! surely the people reckoned me weak and had well-nigh slain me, therefore make not the enemies to rejoice over me and count me not among the unjust people.

(2) He had well-nigh led us astray from our gods had we not adhered to them patiently! And they will know, when they see the punishment, who is straying farther off from the path.
