Aslam

meaning of the following verse of God. There is no animal in the earth of which the maintenance is not upon God. (3) To take birth-control for fear of the birth of daughters. This is unlawful .
The Arabs before Islam used to bury their daughters alive and they feared the birth of daughters. It was prohibited by the Quran. If with the above object, marriage or sexual intercourse is given up, it will be committing sin, but these actions simply without that object are not sinful. If semen is thrown not into uterus with the above object it will be sin. (4) to protect the honour of woman, to keep her neat and clean and to save her from maintaining children. To throw semen out side the uterus with these objects is unlawful.

If you question that the Prophet said. "He who gives up marriage for fear of child-birth is not of us " the answer is that to do Ajal is like not to marry and the meaning of "he is not of us" is that our sunnat or way is better. The Prophet also said : There is secret murder in Ajal and he thereafter recited this verse : When those buried alive will asked for which sin they were killed.
The answer to the above verse is that there is an authentic Hadis about the legality of Ajal. Secret murder in the above Hadis means secret shirk. It is Makruh and not unlawful. Hazrat AH Said : Lifecomes into being after seven stages. Then he read this verse : I have created man from dried clay, then I placed it as semen in its resting places, then I created semen into clot of blood, then the clot of blood into lump of flesh, then the lump of flesh into bones, then the bones covered with flesh and then I created it into another creation. In other words, I infused into it life. Then he recited this verse : When one buried alive will be asked for what fault he was murdered. There is in Sahihs Bukhari and Moslem that Hazrat Jaber said : We used to practice Ajal at the time of the Prophet and the Quran was then being revealed. When this news reached the Prophet he did not prohibit us from it. There is another Hadis reported by Jaber : A man came to the Prophet and said : I have got a slave girl. She serves us and gives water to the palm trees. I cohabit with her but I don't wish that she should conceive. The Prophet said :
Practice Ajal with her if you wish but what has been decreed must come to pass. Then after some time the man came to the Prophet and said : The slave girl has conceived. The Prophet said : What has been decreed must come to pass. This is in Shahihs Bukhari and Moslem.
