Zina is prohibited by the Qur'an, Sunnah (whatever is reported from the Prophet), and Ijma` (consensus). Whoever commits Zina must make Tawbah according to the following conditions:1. Give up the sin 2. Regret what has been done 3. Resolve not to go back to it.In addition, they must be keen to observe the obligatory acts of worship, refrain from committing sins and Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect), increase Istighfar (seeking forgiveness from Allah), and observe the supererogatory acts of worship, because good deeds erase bad ones.
premeditated murder is one of the gravest major sins, which is prohibited by the Qur'an and Sunnah. This woman, by killing her baby, has killed a preserved soul premeditatedly, which is one of the gravest major sins. She must hasten to make sincere Tawbah from this heinous crime; maybe Allah will forgive her and accept her Tawbah.
instigating the mother to get rid of her baby is cooperation in sin and transgression. Thus, this man must make sincere Tawbah and not recommend anyone in the future to do anything but good.
