Fathwa, - Tubal ligation to prevent pregnancy

Question
I am surgeon, I would like to know about doing tubal ligation for
women to prevent conception )pregnancy( most of them already having
between 8 to 10 children and the operation according to their request
)wife and husband(.
Answer
Praise be to Allah, the Lord of the Worlds; and may His blessings and
peace be upon our Prophet Muhammad and upon all his Family and
Companions. Shariah )Islamic Law( highly recommends Muslims to
reproduce prolifically so as to guarantee some advantages for the
Muslim individual, community, and the Muslim country in general, both
in this life and in the Hereafter. Therefore, the Prophet )peace be
upon him( said:Marry women who are loving and very prolific, for I
shall outnumber the peoples by you. ]Reported byAhmadandAbu Dawoud,
and classified as authentic byAl-Albani[ Muslim scholars have
proclaimed that it is prohibited to cut off reproduction for good or
limit the number of children to be born, as such procedures, no doubt,
contradict the objectives of Shariah. Doing so constitutes a response
to the calls made by the enemies of Islam such as the masons and
others in order to weaken the Muslims and reduce their number. This
Fatwa of prohibition was adopted by some contemporary research centers
and authorities, such as the Council of Senior Scholars of Saudi
Arabia. However, there are certain exceptions to this ruling, such as
the case of a woman whose pregnancy causes her health troubles or
whose delivery causes risks to her life. Such forcing necessities are
to be decided by a trustworthy Muslim doctor. Based on that, one is
not allowed to help others cut their reproduction by blocking )or
tying( the womb or any other means even with the consent of the two
spouses. Hence, to do so or just to help others do it is prohibited
according to Allah's Saying: }...Help you one another in Al Birr and At
Taqwa )virtue, righteousness and piety(; but do not help one another
in sin and transgression. And fear Allah. Verily, Allah is Severe in
punishment{ ]5:2[. Allah knows best.
