Younis has claimed that he took this decision after an obscene video was liked from his verified handle.
"Today I have to say with great regret that when I woke up this morning, someone hacked my Twitter account and liked grossly inferior videos from my account," legendary pacer Younis said in a video message from his Twitter handle.
Younis added that he was forced to quit the platform after his account was repeatedly hacked in the past.
"It is a matter of great shame, it is a matter of great regret and discomfort. For me and my family too. I used to think that social media or Twitter is a way of interacting with people. But unfortunately, this man ruined everything.
"By the way, the hacker has not done this for the first time. I do not think this man is going to stop, so I have decided that I will not come on social media after today. I love my family more. You will not see me on social media after today. I am sorry if it hurts anyone," added Pakistan's bowling coach.
