Abu Abdillah Mohammad bin Wahban Al-Hannad narrated from Ahmad bin Ibrahim, from Husain bin Abdillah Al-Za’fraani, from Ibrahim bin Mohammad Al-Thaqafi, from Yahya bin Abdil Quddous, from ALI bin Mohammad Al-TaiALIsi, from Mohammad bin Wakee’ Al-Jarrah, from Faz’eel bin Marzouq, from Atiya Al-Awfai, from Abi Saeed Al-Khodri, who said:
I heard the MESSENGER OF ALLAH (SAWW) say:
On the Day of Judgement, ALLAH (SWT) will order two angels to sit on the SIRAAT’ (the bridge) and guard it. No one will be able to cross the bridge without having a pass issued by ALI BIN ABI TALEB (ASWS). ALLAH (SWT) will order the two angels to stop those who do not have a pass and ask them about it. If they fail to answer, these angels will throw them into Hell, head first.
The PROPHET (SAWW) then referred to this verse from the Quran as evidence,"And stop them for verily they must be questioned" (37:24)
Then I asked the PROPHET (SAWW) , O the MESSENGER OF ALLAH (SWT), may I ransom my father and my mother for you, Please tell me what this pass is?"
The PROPHET (SAWW) replied, ." This is what is written on the pass with a very bright light:
LA ILAHA ILLALLAH (SWT).
MOHAMMADUN RASULULLAH.
ALIUN WALIYULLAH.
