The two Hadiths of 'Fast and you will be healthy' and 'The sleep of a fasting person is an act of worship'

Q 1: How authentic are the following two Hadiths?The Messenger of Allah (peace be upon him) said: Fast and you will be healthy. And: Sleeping in Ramadan is an act of worship.

A: First: The phrase Fast and you will be healthy is a Da`if (weak) Hadith. It was related by Al-Tabarany in Al-Awsat, Abu Nu`aym on the authority of Abu Hurayrah, and Ibn `Ady on the authority of Ibn `Abbas. The Sanad (chain of narrators) of this Hadith contains Nahshal who has been judged by Hadith scholars as Matruk (a narrator whose Hadith transmission was discarded due to unreliability). Second: As far as we know, there is no Hadith that says: "Sleeping in Ramadan is an act of worship." However, one narration which reads: The sleep of a fasting person is an act of worship has been mentioned by Al-Suyuty in Al-Jami` Al-Saghir. He attributed it to Al-Bayhaqy but classified it as Da`if. The Sanad of this Hadith contains Ma`ruf ibn Hassan who has been judged by scholars of Hadith as a weak narrator.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
