1؎: Because the first glance occurs without intention or choice, there is no sin upon it; and since the second glance will be deliberate, there will be sin upon it.
´Narrated Ibn Buraidah:` from his father (from the Prophet (ﷺ)) who said: "O 'Ali! Do not follow a look with a look, the first is for you, but the next is not for you."
Shaykh Dr. Abdur Rahman Freywai
Explanation: 1: That is, if your gaze happens to fall upon someone unexpectedly for the first time, this is excused, but for you to look again will be blameworthy. (And even the first glance must be averted immediately.)
