In the Name of Allah, The Most Gracious, Ever Merciful.
Love for All, Hatred for None.
Oh servants of Muhammad (saw) and devoties of the faith of Muhammad (saw) now forget about your concern as to what your assigned jobs are. Everyone of you is a caller towards Allah. Whatever may be your profession; whatever may be your job. Whichever part of the world you live in. Your first and foremost duty is to call people to the Lord of Muhammad (saw) and change the darkness into light. Turn them from dead bodies into living beings. May Allah do so.
(Excerpts from Friday Sermon of Hazrat Khalifatul Masih IV, February 25, 1983)
