All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
Yes, there are other matters that are legislated by Allah, like choosing a pious wife who is religious and has a good moral conduct. Indeed the correct cultivation can only be achieved on the hands of a pious woman, as a person who lacks something cannot give it to others. In addition to this, when a husband has sexual intercourse with his wife, there is a supplication that should be uttered. If one says this supplication and a child is predestined for them after this sexual intercourse, the child will never be touched or harmed by the devil as confirmed in an authentic Hadeeth; and whoever is protected from the harm of the devil, he has indeed escaped from a great harm, and his cultivation in the future will be easier, and he will be closer to accepting guidance and advice.
Allah Knows best.
