I would like to know if this virtue is authentic
Rewards of fasting the first nine days of Dhul Hijjah:
Rasulullah (sallallahu ‘alayhi wa sallam) said, “If you fast from the 1st till the 7th of Dhul Hijjah, for each fast you will receive the reward of giving one hundred horses fully equipped for jihad, one hundred camels given in charity and freeing one hundred slaves.
Then if you fast on the 8th (Yawmut Tarwiyah), the above rewards is multiplied to one thousand (1000) of each and then if you fast on the 9th as well (The Day of ‘Arafah) the above rewards are multiplied to two thousand (2000) of each as well as the reward of fasting for two years, (and a person will get the same reward for fasting on ‘Aashura)
Imam Ibn ‘Adiy (rahimahullah) has recorded the Hadith in question on the authority of Sayyidah ‘Aaishah (radiyallahu ‘anha).
(Al Kamil, vol. 9 pg. 111)
However many senior Muhaddithun, which include Hafiz Dhahabi and Hafiz Ibn Hajar (rahimahumallah) have declared the Hadith a fabrication. Hafiz Ibn Hajar (rahimahullah) further states [explaining the extreme weakness of this Hadith], “If this Hadith is not a fabrication, then there is no fabricated Hadith in the world” .
(Mizanul I’tidal, vol. 4 pg. 223/4, Lisanul Mizan, vol. 7 pg. 405 -6966-, Tanzihush Shari’ah, vol. 2 pg. 148 and Al Fawaidul Majmu’ah, pg. 84)
The Hadith in question is therefore not suitable to quote.
Although this specific virtue has been deemed a fabrication, fasting has been encouraged in other Hadiths. see here for details.
And Allah Ta’ala Knows best.
