The word(s) "ahead" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And when Musa (Moses) returned to his people, angry and grieved, he said: "What an evil thing is that which you have done (i.e. worshipping the calf) during my absence. Did you hasten and go ahead as regards the matter of your Lord (you left His worship)?" And he threw down the Tablets and seized his brother by (the hair of) his head and dragged him towards him. Harun (Aaron) said: "O son of my mother! Indeed the people judged me weak and were about to kill me, so make not the enemies rejoice over me, nor put me amongst the people who are Zalimun (wrong-doers)."

(2) The hypocrites fear lest a Surah (chapter of the Qur'an) should be revealed about them, showing them what is in their hearts. Say: "(Go ahead and) mock! But certainly Allah will bring to light all that you fear."

(3) He will go ahead of his people on the Day of Resurrection, and will lead them into the Fire, and evil indeed is the place to which they are led.
