In 1970 A.D. I was in Mecca. I hired a taxi to take me round about and to show me what was to be seen. When sometime elapsed I gave some pistachio to the driver to eat for refreshment. So far, he had not eaten that sort of a nut that I gave him. He asked me; what are these things which are of so a good taste!? I said to him; We call it PESTEH. It is the fruit of a small tree of the cashew family. It grows in my home town which is a big village of IsfahanِIran.
As soon as I explained that to him, he stopped his car in a corner. He then came out and prostrated himself with face on the ground in a humble thanks giving to the Lord God! I asked him why did he do so? In answer to me he said:ِ
``When My Lord has given me such a good kind of sustenance, which I do not know how it is produced, and where it is produced, and who is the gentleman who has brought it to me; should I not be grateful for such a bounty of my Lord, and should I not, at least say to him; thank you very much my Lord!?''
