This book is about the life of Hazrat Mirza Tahir Ahmad, Khalifatul Masih IV (may Allah have mercy on him). He was a fortunate son of a devotee mother (Hazrat Umm e Tahir), for whom she would pray all the time saying,
'O' God! May my Tahiri be Your devotee!
Writing about Hazrat Umm e Tahir's (may Allah be pleased with her) devotion and righteousness, Hazrat Syeda Mahr Appa Sahiba said:
Dear Tahir is the only son of Phuphi Jaan (paternal aunt). She would always pray with great pathos herself and also asked others to pray that as she had only one son, may God make him a servant of faith. She would say that she had devoted him in the cause of God and may God make him a devotee in the true sense.
She would tearfully repeat these words:
'O' God! May my Tahiri be Your devotee! May he be devout and reverent! Make hima servant of faith. Immerse him in Your ardent love and ardent love of the Holy Prophet (peace and blessings of Allah be on him) and of the Promised Messiah (peace be on him).
