In our society, there are mixed gender gatherings at both religious and non-religious occasions. As oppose to the time of our ancestors, mixed gender gatherings have become norm and anyone in opposition to these is considered out of touch with the modern life-style. In some places, one may just accept the way of life and participate under the conditions of dissimulation ‘Taqayya’, however, in certain circumstances where one is not compelled, one must seriously think if it’s necessary to be part of mix gender gatherings? So, if one has an option to please his Creator at a little cost of being ‘unpopular’ then why not? – for the sake of submitting to the Divine Commands, as explained by the Ahl Al-Bayt‑asws. To this end, we have already covered the bashfulness and the concept of ‘Hijab’ in a short article, ‘Hijab’ here, we just present a single which is suffice for the subject.
Muhammad Bin Musa Bin Al Mutawakkal narrated to us, from Ali Bin Al Husayn Al Sa’ad Abady, from Ahmad Bin Abu Abdullah Al barqy, from Al Hassan Bin Mahboub, from Abu Ayoub Al Khazaz, from Abu Ubeyda Al Haza’a,
حدثنا محمد بن موسى بن المتوكل قال: حدثنا علي بن الحسين السعد آبادى قال حدثنا احمد بن أبى عبد الله البرقي قال حدثنا الحسن بن محبوب عن أبى أيوب الخزاز عن أبى عبيدة الحذاء عن أبى جعفر محمد بن علي ” ع ” قال: الحيض من النساء نجاسة رماهن الله بها، قال: وقد كن النساء في زمن نوح إنما تحيض المرأة في كل سنة حيضة حتى خرجن نسوة من حجابهن وهن سبعمائة امرأة فانطلقن فلبس المعصفرات من الثياب وتحلين وتعطرن ثم خرجن فتفرقن في البلاد فجلسن مع الرجال وشهدن الاعياد معهم وجلسن في صفوفهم فرماهن الله بالحيض عند ذلك في كل شهر أولئك النسوة باعيانهن فسالت دمائهن فخرجن من بين الرجال وكن يحضن في كل شهر حيضة، قال: فاشغلهن الله تبارك وتعالى بالحيض وكثر شهوتهن،
Abu Ja’far Muhammad-asws Bin Ali-asws has said: ‘The menstruation from the women is an impurity which Allah-azwj has Thrown at the women. And the women in the era of (Prophet) Noah-saww used to menstruate in every year, only once, until the women came out from their veils, and there were seven hundred women. So, they wore yellow dresses, and made up, and applied perfume, then went out dispersing in the cities. So, they gathered with the men and participated in the festivals with them, and sat in their rows. Therefore, Allah-azwj Cast the menstruation at them during that to be once every month. Those were the women who used to sell themselves. So, their blood flowed, and they went out from in between the men, and it became so that their menstruation occurred once in every month’. He-asws said: ‘So Allah-azwj Blessed and High got them to be occupied with the menstruation due to the frequency of their lustful desires’.
قال: وكان غيرهن من النساء اللواتى لم يفعلن مثل فعلهن كن يحضن في كل سنة حيضة قال فتزوج بنو اللاتى يحضن في كل شهر حيضة بنات اللاتى يحضن في كل سنة حيضة، قال: فامتزج القوم فحضن بنات هؤلاء وهؤلاء في كل شهرحيضة، قال: وكثر أولاد اللاتى يحضن في كل شهر حيضة لاستقامة الحيض، وقل أولاد اللاتى لا يحضن في السنة إلا حيضة لفساد الدم قال: فكثر نسل هؤلاء وقل نسل أولئك.
He-asws said: ‘And the other women who did not do the like of what they had done, their menstruation occurred once in every year. So, the sons of those who menstruated every month married the daughters of those who were menstruating once every year with a menstruation. Thus, the people intermingled, and the daughters of these ones and those ones menstruated every month with a menstruation. And the children of those who menstruated once in every month with a menstruation were numerous due to the occurrence of the menstruation, and the children of those that did not menstruate in a year except for one menstruation were less due to the spoiling of the blood. Thus, the offspring of these ones were numerous, and the offspring of those ones were a few’.
