Sayyiduna Hudhayfah (may Allah be pleased with him) narrates: I performed prayer one night behind the Prophet (peace and blessings of Allah be upon him), and whenever he reached a verse mentioning mercy, he would pause there and ask for that mercy, and whenever he recited a verse mentioning punishment, he would pause there and seek refuge from that punishment.
