The report which says one should say “ Wa ana ‘ala dhaalika min al-shaahideen (And I am one of those who testify to that)” after reciting Soorat al-Teen is da’eef (weak)

 

where can I find it ?
Jazzakallahu Khayrun

Praise be to Allaah.

Al-Tirmidhi, may Allaah have mercy on him, said in his Sunan:
“Ibn Abi ‘Umar told us, Sufyaan told us from Ismaa’eel ibn Umayyah who
said: ‘I heard a Bedouin Arab man say, “I heard Abu Hurayrah say, narrating
this, ‘Whoever recites “Wa’l-teeni wa’l-zaytoon (By the fig, and
the olive)” [al-Teen 95:1 – interpretation of the meaning] then recites “Alaysa
Allaahu bi ahkam il haakimeen (Is not Allaah the Best of judges?)” [al-Teen 95:8
– interpretation of the meaning], let him say, “Balaa wa ana ‘ala
dhaalika min al-shaahideen (Yes indeed, and I am one of those who testify to
that).”’”’” Abu ‘Eesa said: “This hadeeth was narrated
with this isnaad from this Bedouin from Abu Hurayrah, but his name is not given.”
Thus al-Tirmidhi (may Allaah have mercy on him) explained the fault in this isnaad, which
is the fact that this Bedouin is not known (jahaalah). On this basis, the isnaad is
da’eef (weak), and the hadeeth is not saheeh. Abu Dawood (may Allaah have mercy on
him) also narrated this report (753) from the same Bedouin. Al-‘Allaamah al-Albaani
also classed the hadeeth as da’eef in his book Da’eef al-Jaami’, no.
5784. As the hadeeth is not proven, we cannot follow it. And Allaah knows best.
