Allah subhanahu wa ta‘ala is qabil al-tawb: the acceptor of penitence. Innahu kana bi’l-awwabina ghafura: He is ever Forgiving of those who turn to Him. Faced with the evidence of His overpowering might, and of His power to remove His protection from the violence of nature, our hearts tremble. And in this there lies our hope. Allah himself says, in a Hadith Qudsi:  ‘Son of Adam! So long as you call upon Me and ask of Me, I shall forgive you for what you have done, and I shall not mind. Son of Adam! were your sins to reach the clouds of the sky and were you then to ask forgiveness of Me, I would forgive you. Son of Adam! Were you to come to Me with sins nearly as great as the earth and were you then to face Me, ascribing no partner to Me, I would bring you forgiveness like unto it.’ [Tirmidhi] The divine name al-Hafiz, the Protector, is the one we seek refuge in against the name al-Muntaqim, the Avenger. This is the meaning of the Prophetic du‘a –A‘udhu bika mink: ‘I seek Your protection from You.’
