Is this narration authentic?
ليغسل موتاكم المأمونون
Imam Ibn Majah (rahimahullah) has recorded this Hadith on the authority of Sayyiduna ‘Abdullah ibn ‘Umar (radiyallahu ‘anhuma).
(Sunan Ibn Majah, Hadith: 1461)
However the chain consists of a narrator who has been declared extremely weak. Imams Ahmad and Daraqutni (rahimahumallah) have declared him a fabricator.
(Refer: Zawaid Ibn Majah, Hadith: 483, Mizanul I’tidal, vol. 4 pg. 14)
Nabi (sallallahu ‘alayhi wa sallam) said:
“The trustworthy [i.e. those who will not expose any defects/faults of the deceased] ones should give ghusl to the deceased.”
See here for the virtue of giving ghusl to the deceased, on condition that a person conceals the faults of the deceased.
And Allah Ta’ala Knows best.
