Harry Randall's wife, Ruth, had tuberculosis in both lungs and, having been intensely affected by his first meeting with ‘Abdu’l- Bahá, Harry decided to ask ‘Abdu’l-Bahá for help. On Sunday, 28 August, Harry went to the home of Maria Wilson, where ‘Abdu’l-Bahá was staying in Malden. Harry thought that if ‘Abdu’l-Bahá was all the Bahá’ís were saying He was, then surely He could cure Ruth's illness. When Harry arrived at the Wilson home, it was packed with people. He managed to get into the house and explained his request to one of the Master's secretaries. The secretary said that ‘Abdu’l-Bahá was reading His mail from Persia and that if He wished to see Harry, He would call for him. The secretary informed Harry that over 100 others had also either asked to see the Master or wanted to invite Him somewhere and that He never accepted any until the spirit moved Him to do so. With so many people ahead of him, Harry was pessimistic of seeing ‘Abdu’l-Bahá, particularly since the Master didn't even know he was there. He turned glumly, noticed Harlan Ober, so went over to talk with him. Suddenly, a voice called, "‘Abdu’l-Bahá will see Mr. Randall." Shocked, Harry went to the porch where he found ‘Abdu’l-Bahá still reading His mail. When the Master finally looked up, Harry started to say, "I wanted to know if you . . ." , but ‘Abdu’l-Bahá simply said, "Yes, I will come to see your wife this afternoon." At four o'clock that afternoon, Harry returned to the Wilson home with a car and the chauffeur to take ‘Abdu’l-Bahá to see Ruth. Standing there ready to go with ‘Abdu’l-Bahá together with His complete set of Persian attendants and Harlan and Grace Ober. Ruth described what happened next:
‘Abdu’l-Bahá clapped His hands and the Persians got into the car, Grace and Harlan and my husband were standing on the sidewalk. The Master pointed to the Ober's and said: "You wait here" and motioned Harry to sit on the floor of the car. This did not please Harry but he did it. ‘Abdu’l-Bahá laughed and joked and seemed very happy. Several times He looked at Harry and laughed heartily. Harry knew later in life that he was being taught a lesson in humility. When they came to the driveway He ordered the chauffeur to stop and wait. They all got out and walked up the driveway.Upon reaching the porch ‘Abdu’l-Bahá changed to a white aba and a white turban. My mother opened the door and ‘Abdu’l-Bahá walked right through the house to the porch where I was lying . . . When He opened the screen door He looked directly at me in that moment I was aware of the Fact that I had known him always. We had invited a number of people to meet Him and mother introduced them to Him and when she came to me He pushed His hand toward me and said: "I know her well!" He took Margaret (Ruth's five-year-old daughter, later named Bahiyyih by the Master) in his arms and asked her if she was happy. She was a little frightened because she had never seen such a long beard or such a wrinkled countenance . . . Then He asked me why I thought I was sick and I made some senseless reply. He asked Dr. Farid to take my pulse. Then ‘Abdu’l- Bahá came and leaned over me and placed His hand on my forehead. He looked deep into my eyes. At that moment I knew that my life was a book which He could read at will. He then told me to do the same things that my physician told me, besides telling me to eat my noonday meal in the sun . . . He arose after a few minutes and went into the house. When He came to the library door he looked in and raised his eyes heavenwards saying: "This is a beautiful house, someday it will become a beautiful home." Goodbyes were said and they walked down the driveway to the waiting car. Again He placed my husband on the floor of the car.
As they departed, ‘Abdu’l-Bahá, through one of his interpreters, told Harry "not to mind if your wife does not like sweet things, that she will when she is better." Then ‘Abdu’l-Bahá told Harry that he should always keep her in the light. Baffled by these comments, when he returned home later, Harry asked Ruth what ‘Abdu’l-Bahá meant. Each Sunday, Harry had brought home a box of fancy chocolates as a special treat for her and at that moment, she tearfully told him that she always struggled to eat even one of them to please him. Then she told him about the light: that because, as a child, she had to walk down a dark street each week to get the beans for dinner, she had been afraid of shadows ever since. After hearing these admissions, Harry was somewhat amazed at ‘Abdu’l-Bahá's depth of understanding. Ruth wrote that within hours, she was feeling better. Two weeks later, she visited a regular doctor. He examined her and exclaimed, "What have you been doing? You are so well!" Soon Ruth was completely cured of tuberculosis. This was Harry's second big step towards becoming a Bahá’í.
