Why did MS Dhoni choose number 7 jersey?

Despite the West Indies cricketer being a superstar T20 cricketer, Chris Gayle wore jersey number 333, which was his highest score in Test cricket. During the IPL, Sri Lankan cricketer Muttiah Muralitharan was seen wearing jersey number 800, which was his record number of Test cricket wickets. These were two instances where two legendary cricketers changed jersey numbers during their career but MS Dhoni chose the same number 7 jersey and stuck to it till the end.

Then why did Mahendra Singh choose this prestigious number 7?

Mahendra Singh Dhoni said in an event, "This was the time or day when my parents decided that I had to come to earth. So I was born on July 7. July is also the seventh month. It's been 81 years." And if you do 8-1, it becomes 7. So when they asked me my number, it was very easy for me to tell.

After Dhoni's international career ended, BCCI retired his jersey number. Apart from this, BCCI had also retired the number 10 jersey after the retirement of Sachin Tendulkar.
