Q- What is status of following narration? ابو بكر مني وانا منه وابو بكر أخى في الدنيا والآخرة
This narration appears in Musnadul Firdaws of Imam Daylami. (Musnadul Firdaws, Hadith: 1780)
However, the chain consists of fabricator. The narration is therefore not suitable to quote.(Refer: Faydul Qadir, Hadith: 72, Al Mudawi, Hadith: 53. Also see: Lisanul mizan, vol. 5 pg. 116/117, number: 4663)
There are many authentic virtues of Sayyiduna Abu Bakr (radiyallahu ‘anhu). These should be quoted instead. 1 example below
“No one has done any favour to me except that I have reciprocated him, except for Abu Bakr (radiyallahu ‘anhu). For the favours that he has done to me, Allah will recompense him. No person’s wealth has benefitted me as much as the wealth of Abu Bakr (radiyallahu ‘anhu). Imam Tirmidhi (rahimahullah) in his Sunan, Hadith: 3661.Imam Tirmidhi (rahimahullah) himself has declared this Hadith as sound (hasan)
And Allah Ta’ala Knows best.
