I have previously written this Sign in the closing pages of Tadhkiratush-Shahadatain. The Sign is that in October 1903 I had decided to write a booklet about the martyrdom of Sahibzadah ‘Abdul-Latif and Sheikh ‘Abdur-Rahman— who were put to death with the utmost cruelty. I had proposed Tadhkiratush-Shahadatain as the title of the booklet. However, it so happened that I began to suffer from renal colic. I had intended to finish the booklet by 16 October 1903, for it was necessary to go to Gurdaspur to appear in a criminal case which one of my opponents had filed against me. At that time, I supplicated before God, ‘O my Allah! I want to write a booklet about the blessed martyr ‘Abdul-Latif and renal colic has started. Grant me cure.’
I had once before suffered from renal colic for ten continuous days and had come to the verge of death on account of it. On this occasion, too, I feared the same. I told the members of my family that I would pray and they should say Amin. Then, in this state of severe pain, I prayed for the cure, and they said Amin. So I say under oath in the name of God Almighty, oath in whose name is greater than all evidence, that I had not yet completed my prayer when I was overtaken by drowsiness and I received the revelation:
[Peace is the word from the Merciful Lord.]
I immediately communicated this revelation to the members of my family and to all those present at the time. Allah, the All-Knowing is well aware that before six o’clock in the morning I recovered fully and I completed half the book the same day. 
[So Allah be praised for all this]. See the last part of Tadhkiratush-Shahadatain.
