Sahih Muslim Book 4, Hadith Number 801.

Chapter : The placing of the right hand over the left hand after the first Takbir in prayer (Takbir-i-Tahrima) below the chest and above the navel and then placing them opposite the shoulders in prostration.

Qatida has narrated a Hadith like this with another chain of transmitters. In the Hadith transmitted by Jarir on the authority of Sulaiman, Qatida’s further words are: When (the Qur’an) is recited (in prayer), you should observe silence, and (the following words are) not found in the Hadith narrated by anyone except by Abu Kamil who heard it from Abu ‘Awina (and the words are): Verily Allah vouchsafed through the tongue of the Apostle of Allah (may peace be upon him) this: Allah listens to him who praises Him. Abu Ishaq (a student of Imam Muslim) said: Abu Bakr the son of Abu Nadr’s sister has (critically) discussed this Hadith. Imam Muslim said: Whom can you find a more authentic transmitter of Hadith than Sulaiman? Abu Bakr said to him (Imam Muslim): What about the Hadith narrated by Abd Huraira, i.e. the Hadith that when the Qur’an is recited (in prayer) observe silence? He (Abu Bakr again) said: Then, why have you not included it (in your compilation)? He (Imam Muslim) said: I have not included in this every Hadith which I deem authentic; I have recorded only such ahadith on which there is an agreement (amongst the Muhaddithin apart from their being authentic).
