That websites seems very unreliable. Does a scholar or a layman run it?
Let's look at one hadith he has posted which actually deals with the issue of prayer and is not a general hadith he is trying to use:
Rasulullah (sallallaahu alayhi wa sallam) has clearly differentiated between the sitting posture of men and women in salat.
عن عبد الله بن عمر قال قال رسول الله صلى الله عليه وسلم إذا جلست المرأة في الصلوة وضعت فخذها على فخذها الاخرى وإذا سجدت الصقت بطنها في فخذيها كالستر ما يكون لها وان الله تعالى ينظر إليها ويقول يا ملائكتى اشهدكم انى قد غفرت لها
Abdullah Bin Umar (radiyallaahu anhu) reports that the Prophet (sallallaahu alayhi wa sallam) said: "When a women sits in salaat, she should place the thighs of one leg upon the thighs of the other and when she makes sajda, she should attach her belly to her thigh so that it is as concealing as possible, for indeed Allah Ta'ala looks at her saying: 'O my angels, I make you witness that I have indeed forgiven her". (Al-Baihaqi, vol 2, pg 223, Idara Al-Taleefaat)
Let me put forth what scholars have said about that hadith.
al-BayhaQi said:
ضعيف لا يحتج بمثله
Weak, evidence is not established with the likes of it.
The very Imaam who recorded the narration is calling it weak.
I wonder why the author of the website omitted that fact.
al-BayhaQi reports two narrators in it who are weak
أبو مطيع
and
عطاء بن عجلان
He says they are weak.
Perhaps the author of the website should learn first and then make Wordpress blogs. May Allaah guide him.
