The Hadeeth, “If you see poverty coming to you then say, ‘Welcome, O sign of the righteous’”

This
hadeeth was narrated by al-Daylami in Musnad al-Firdaws – as al-Hafiz
al-‘Iraqi said – from the report of Makhool from Abu’l-Darda. It is a da’eef
(weak) hadeeth, for Makhool did not hear anything from Abu’l-Darda. 

See
Takhreej Ihya ‘Uloom al-Deen, 4/191. 

It was
also narrated by Abu Na’eem in al-Hilyah (6/5) from the report of Mujahid
from Ka’b al-Ahbar. 

And he
narrated it in 6/37 from the report of Qutadah from Ka’b al-Ahbaar. 

Both
isnads (chains of narration) include Ishaq ibn Bishr al-Kahili, who is
matrook [i.e., his hadeeth is not accepted]. Abu Zar’ah said: he used to
tell lies.  

Al-Daraqutni said he is kaththab matrook (i.e., a liar whose hadeeth is not
to be accepted). Al-Azdi said: his hadeeth is to be rejected and is not
valid, and he was accused of lying. Ibn Hibban said: he used to fabricate
hadeeth and attribute them to trustworthy narrators (thiqat); his hadeeth
should not be written down except by way of amusing oneself with something
weird. 

See
al-Jarh wa’l-Ta’deel, 2/214; al-Du’afa wa’l-Matrookeen by Ibn al-Jawzi,
1/100. 

He is one
of the storytellers and time-wasters. Al-Thahabi said in his biography of
him: the shaykh, the scholar, the storyteller, the weak narrator (da’eef),
the time-waster, Abu Hudhayfah Ishaq ibn Bishr ibn Muhammad ibn ‘Abd-Allah
ibn Salim al-Hashimi, whose teacher was al-Bukhari the author of al-Mubtada,
which is a well known book in two volumes. Ibn Jareer and others narrated
from him, and in it he spoke of weird and disastrous things.
