What is the basis for rejecting the narrations in Sunni texts regarding placing one hand over the other during prayer? Could you provide references from Shia sources that support the practice of opening hands during prayer?
1. We follow the authentic Sunnah of the Prophet Muhammad (SAWA) taken from the most authentic and most knowledgeable source who are the Prophet’s own Progeny (Ahlul Bayt). We never accept fabricated narrations no matter what was the reason behind the fabrication.
2. There no authentic narrations that the Prophet Muhammad (SAWA) ever folding hands during are Salah. This fact was admitted by many leading Sunni scholars including Al-Azhar Sunni scholars in the book (Fiqh Al-Sunnah) and many other Sunni scholars.
3. No Sunni scholar could say that folding hands in Salah is obligatory. Imam Malik of the Maliki Sunni sect rejected folding hand in Salah.(Al-Mughni by Ibn Qudamah;514).
4. Had they have any authentic narration that the Prophet ever hooded his hands during Salah, they should have said that it is an obligatory act as all Muslims say that following the acts of the Proohet (SAWA) is obligatory.
5. Ahlul Bayt (AS) who are the most knowledgeable and the most authentic after the Prophet (SAWA) have clearly objected on folding hands during Salah and said that it is an act came from Non Muslims. Ahlul Bayt (AS) ordered Muslims not to fold hands during Salah (Al-Khisal by al-Sadouq , V.2 , P. 161). Also in Qutb Al-Isnaad 95 and Biharul Anwaar, V. 10 m P. 277.
