Mahindra Group Chairman Anand Mahindra on Monday took to Twitter to share a shayari (couplet) revolving around mobile phones and credited poet Gulzar for penning it down. However, several users pointed out that Gulzar was not behind the couplet. A user also posted a screengrab showing the couplet on Facebook Page 'NotByGulzar' that documents poetry wrongly credited to Gulzar.
