Is the hadith reported in Musnad Ahmad concerning the Companion Zahir, which mentions, "he embraced him from behind" and "he spared no effort in pressing his back against the Prophet's chest, may Allah bless him and grant him peace," authentic, and has it been reported with other wordings in other hadiths?

The hadith highlights the Prophet's good character, humility, and jesting with his companions. The incident occurred publicly in the market, and embracing from behind is a known playful gesture. People of sound mind understood the hadith in this way, while stubborn individuals attempted to distort it due to their deviant understanding based on their desires and Freudian materialism.
