Sayyiduna Hudhayfah (may Allah be pleased with him) narrates that I prayed one night with the Messenger of Allah (peace and blessings be upon him). Whenever he recited a verse of mercy, he would pause and ask Allah Almighty for mercy, and whenever he recited a verse of punishment, he would pause and seek refuge with Allah Almighty from His punishment. This is the hadith of Abu Musa.
