That Malik was asked about placing

Q 5: Is it Sunnah to place the right hand over the left one on the chest while performing Salah (Prayer)?

A: The right hand should be placed on the back of the left hand, wrist, and forearm on the chest during recitation in the standing position at the beginning of Salah and whilst standing up straight after Ruku`(bowing) until performing Sujud (prostration). This is the way (Part No. 6; Page No. 369) the Prophet (peace be upon him) performed Salah and it is his practical Sunnah (acts, sayings or approvals of the Prophet).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
