Is there a sound, sharia-based text indicating that whoever kisses the Black Stone will enter Paradise without reckoning?

The saying, "Whoever kisses the Black Stone enters Paradise without reckoning," is not found in the books of Sunnah, nor does it have any origin from the Prophet, peace and blessings be upon him, and it is impermissible to attribute it to him.

What is authentically established regarding its virtue is that touching it expiates sins and that it will testify on the Day of Resurrection for whoever touched it rightfully. This is as narrated in the Hadith by Tirmidhi from Ibn Abbas, may Allah be pleased with him, that the Prophet, peace and blessings be upon him, said: "By Allah, Allah will resurrect it on the Day of Resurrection with two eyes with which it sees, and a tongue with which it speaks, testifying for whoever touched it rightfully."

It is also authentically established that touching the Black Stone and the Yemeni Corner is an expiation for sins, as narrated in the Hadith by Tirmidhi from Ibn Umar, may Allah be pleased with both of them.
