Assalam-o-Alaikum wr wb.
Hadees-e-mubarikah hay keh "anaa madina'tul ilm" (mai'n ilm ka sheher hoo'n).
agar likhna or parhna ilm hai'n to kaisay mumkin hay keh yeh uloom "madina'tul ilm" mai'n naa ho'n?
poori kaynaat kay tamam zahiri or batini uloom mai'n say sirf aik aisa ilm hay jis kay mutaliq quran paak mai'n irshad-e-Rabbani hay keh....
or nahee'n sikha'ee ham nay is Nabi ko shairi, or nahee'n thi is kay shayan-e-shan yeh cheez.....
soorah yaseen ayat 69.
*Sirf shairi ka ilm Allah paak nay Rasool Allah s.a.w.a.w., ko nahee'n sikhaya or iss bat par quran khud gawah bhi hay. *
ab agar kisi ko yeh sabit karna ho keh fulaa'n fulaa'n uloom bhi madina'tul ilm mai'n nahee'n thay to iss kay liay yaqeenan hawala darkar hay wagarnah Rasool Allah s.a.w.a.w., ki Hadees-e-Mubarikah or Quran ki ayat yeh baat samajh lainay kay liay kaafi hai'n keh shairi kay ilawah kaynat kay tamam uloom "shehr-e-ilm s.a.w.a.w.," mai'n mojood hai'n.
I have been in Management Consultancy for over 10 years now, I personally knew some very successfull business owners who still cannot read or write and they have employees who read and write for them, Although it is very risky, but the point here is , IQ and Knowledge of doing certain thing is not depended on reading and writing skills of the one, although it can be an added value but not the mandatory..
Quran is live Miracle, I recall an incident, where a French Sailor ( might be navy person) heard the verses where, Allah Subhan.o.tala was referring the the darkness by giving the example, where the night was cloudy, it was raining and the waves of the ocean was covering every thing. Being a sailor he can imagine the situation, he asked the sailor did ur Prophet (SAAW ever went on voyage, the reciter said no, he never been on voyage, the Sailor said then how come he can give such example, the reciter said, It was not his words, they are the word of Allah which he are reavled to him, to delived it to us.
It is said that the Sailor, did bit more research and accepted Islam.
( i don't know if the above incident is true or not, but it surely tells u the source of the wisdom and knowledge of Prophet (SAAW))
