1194. hadíth
4408 - وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ : "لاَ تُجَامِعْ فِي أَوَّلِ اَلشَّهْرِ وَ لاَ فِي وَسَطِهِ وَ لاَ فِي آخِرِهِ فَإِنَّهُ مَنْ فَعَلَ ذَلِكَ فَلْيُسَلِّمْ لِسِقْطِ اَلْوَلَدِ فَإِنْ تَمَّ أَوْشَكَ أَنْ يَكُونَ مَجْنُوناً أَ لاَ تَرَى أَنَّ اَلْمَجْنُونَ أَكْثَرُ مَا يُصْرَعُ فِي أَوَّلِ اَلشَّهْرِ وَ وَسَطِهِ وَ آخِرِهِ ".
Hadith.4408 - Imam Jafar ibn Muhammad Al-Sadiq (as), said: "Do not have intercourse at the beginning of the month, in its middle, or at its end. For whoever does so should prepare himself for the possibility of miscarriage. And if the child is born, it is likely to suffer from mental instability. Do you not see that most cases of insanity occur at the beginning, middle, and end of the month?"
