"As-salaamu alaikum wa Rahmutullahi wa Barakatuh, for I will not see you after this day. May Allah have mercy upon you, but I do not like to be known, and I love to be solitary, for I am in deep anxiety when I am with people. So do not ask about me, and do not call upon me, but know that you are in my heart even if I do not see you nor you see me. Mention me and pray for me, for I will mention you and pray for you, if Allah, Exalted is He, so wishes. So go away from here."
