Placing the right hand over the left one while standing during Salah
Placing the right hand over the left on the chest while standing during Salah is an authentic Sunnah (supererogatory act of worship following the example of the Prophet):
Wa’il ibn Hujr said that he saw the Prophet (peace be upon him) raising his hands when starting Salah and made Takbir (saying: "Allahu Akbar [Allah is the Greatest]"). Then, he (the Prophet) wrapped his cloak around himself and placed his right hand over his left hand.
Ibn Hibban and
Ibn Khuzaymah) The Hadith is supported by the Hadith narrated on the authority of
Qubaysah ibn Hulb Al-Ta'iy from his father and reported by
Imam Ahmad in his Musnad through a Hasan (good) Sanad (chain of narrators).May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
