In one of his early battles with Tendulkar during the Sahara Cup in Canada, Saqlain thought it would be a good idea to sledge the champion batsman. As it panned out, the wily off-spinner sledged to never sledge the then Indian captain again.
"I was new when I sledged him for the first time. If I recall correctly, it was the 1997 edition. Sachin quietly came up to me and said 'I never misbehaved with you, why are you misbehaving with me'? I got so embarrassed that I did not know what to say to him," Saqlain told PTI over phone on Tendulkar's 47th birthday.
"He said to me 'I rate you high as a person and player'. I was so embarrassed that I never sledged him again. I can't tell you what I said to him but I apologised to him after the game.
"Thereafter, even when he was smashing me all over, I never thought of sledging him," recalled the 43-year-old, describing Tendulkar as one of the most humble human beings he met.
After the Sahara Cup, which ran from 1996-98, both were in the middle of arguably their most memorable battle during the Chennai Test of 1999, when Pakistan eked out a 12-run win despite an "unbelievable" 136 from Tendulkar.
Saqlain got the better of Tendulkar in both the innings and his match haul of 10 wickets made all the difference.
Tempers were running high in that high stakes game but even then Saqlain said he never tried to engage Tendulkar verbally.
"In that 1999 Test, no words were exchanged. We both were determined and focused to win the game for our countries. We put our heart and soul in it (on day four).
"I consider myself lucky that my name was attached to Sachin's cricketing career with that match. The only difference that day was that god was on my side.
"Otherwise, the way he was playing, it was unbelievable. The ball was reversing but he played Wasim Akram with such confidence," said the inventor of 'Doosra'.
Saqlain was expected to play a lot more than the 49 Tests and 169 ODIs he eventually did.
Asked how he would rate his rivalry with Tendulkar, the Saqlain said: "I would say it was 50-50. I dismissed him multiple times but he also took me to the cleaners. Even on that day four in Chennai, he scored a hundred in a difficult situation. It was like a dangal going on between us."
