In the name of Allah, the Most-Merciful, the All-Compassionate
As-Salaam Alaikum Wa-Rahmatullahi Wa-Barakatuhu
"May the Peace and Blessings of Allah be Upon You"
Praise be to Allaah, we seek His help and His forgiveness. We seek refuge with Allaah from the evil of our own souls and from our bad deeds. Whomsoever Allaah guides will never be led astray, and whomsoever Allaah leaves astray, no one can guide. I bear witness that there is no god but Allaah, and I bear witness that Muhammad is His slave and Messenger.
