(Fatwa: 603/603=M/1430)
It is written in Bahishti Zewar that a woman should take forty clovers and recite the below mentioned verse seven times on each. Then once she comes out of her menstruation and takes bath, she should start eating one peace while going to bed without taking water and sometime visit the husband. The verse is:
أَوْ كَظُلُمَاتٍ فِي بَحْرٍ لُجِّيٍّ يَغْشَاهُ مَوْجٌ مِنْ فَوْقِهِ مَوْجٌ مِنْ فَوْقِهِ سَحَابٌ ظُلُمَاتٌ بَعْضُهَا فَوْقَ بَعْضٍ إِذَا أَخْرَجَ يَدَهُ لَمْ يَكَدْ يَرَاهَا وَمَنْ لَمْ يَجْعَلِ اللَّهُ لَهُ نُورًا فَمَا لَهُ مِنْ نُورٍ
In-shaAllah, she will be blessed with children.
