An Important Approach Towards The Contemporary Sciences-[Brief Clarifications By Shaikh Uthaymeen, Shaikh Abdul Azeez Bin Baaz and Shaikh Saaleh Aala Ash-Shaikh]
In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Shaikh Uthaymeen [rahimahullaah] said: We do not say: “We do not give consideration to anything stated by the people in the subject matter regarding medicine, astronomy and the celestial bodies”; however, we do not accept everything they say. If what they say opposes the Book and the [authentic] Sunnah, then indeed we do not accept their statements; [rather] we take [i.e. believe and affirm without any doubt] that which is conveyed in the Book and the [authentic] Sunnah, and we say, ‘An era will come in which the people will bear witness to the falsity of those statements of theirs – at present – that are in opposition to the Book and [authentic] Sunnah and [bear witness] to the soundness of that which has been conveyed in the Book and the [authentic] Sunnah. [End of quote. Ref 1]
The Messenger [sallal laahu alayhi wasallam] said: Verily, the creation of each of you is brought together in his mother’s womb for forty days as a drop [of water, semen], then he is a clot for a similar period, then a morsel for a similar period…. [An-Nawawi’s Forty Hadeeth. Hadeeth 4]
Shaikh Saaleh Aala Ash-Shaikh [hafidhahullaah] said: It is well known that during that era, the Sahaabah did not know these stages [of development of the human being in the womb] through experimental knowledge, vision [i.e. by way of the naked eye] or other than that; rather it was simply [a statememt of the Prophet] which they [believed and affirmed]. They were scholars by way of the revelation sent down to the Prophet [sallal laahu alayhi wasallam] and not by way of experimentation [examination]. [Ref 2]
The Correct Manner In Which We Should Approach The Contemporary Sciences
Imaam Abdul Azeez Bin Baaz [rahimahullaah] said: Indeed, that which is stated by the astronomers about the celestial bodies, their sizes and the distance between them, and that which is said about the earth [i.e. by the geologists etc] is categorized into three affairs:
 That which is backed by the sound knowledge based proofs [i.e. the Sharee’ah], therefore it is accepted.
 That which the knowledge based proofs [i.e. the sharee’ah] declares to be false, therefore it is rejected.
 That which there is no proof to either accept or reject it, therefore it is unproven until a person from the people of knowledge [i.e. upright scholars of Ahlus Sunnah] examines it [i.e. examines what it indicates based on the Book and Sunnah] to show whether it should be accepted or rejected. As for accepting it without [sound] investigation and observation, but merely accepting it by blindly following them [i.e. the astronomers, geologists etc], then this is impermissible because of the numerous mistakes that occur as a result of that, and speaking -without knowledge – about Allaah and that which He has created [i.e. the entire universe and all that is within it] [Ref 3]
