the evidence that looking at all women is not forbidden is that a single woman appears before men and is not shy about that. if it was forbidden when she was young it would not be permissible if she became a single woman. however it is something that transgressors have gone to extremes in to the point of jealousy bad character and narrowmindedness so it has become for them like an obligatory right.
والدليل على أن النظر إلى النساء كلهن ليس بحرام، أن المرأة المعنسة تبرز للرجال فلا تحتشم من ذلك. فلو كان حراما وهي شابة لم يحل إذا عنست، ولكنه أمر أفرط فيه المتعدون حد الغيرة إلى سوء الخلق وضيق العطن، فصار عندهم كالحق الواجب.
