Sahih: Jewish boy who got sick accepted Islam.

Classification: Sahih (authentic)

From Anas (may Allah be pleased with him) who said: “A Jewish boy used to serve the Prophet (peace and blessings of Allah be upon him), and he fell sick. The Prophet (peace and blessings of Allah be upon him) went and visited him. He sat by his head and said, ‘Enter Islam.’ The boy looked at his father, who was present. (His father) said, ‘Obey Abu’l-Qaasim (meaning the Prophet peace and blessings of Allah be upon him).’ So the boy entered Islam and the Prophet (peace and blessings of Allah be upon him) left saying, ‘Praise be to Allah Who has saved him from the Fire.’”

Fabricated: Speaking in the Masjid eats up good deeds...

Classification: Fabricated.

"Speaking in the masjid eats up good deeds just like the fire consumes dry wood (or just like cattle eat grass)"

Note: Although the above hadith is fabricated and a lie, this does not mean Muslims should participate in idle talk at the Masjid but instead they should use their time at the Masjid properly in the worship of Allah.
