La ilaha illa anta subhanaka

Assalamualaikum wbt,

Sayyiduna Sa'd ibn Waqas ( radi Allahu anhu ) reported:

the Holy Prophet (sallal laahu alaihi wasallam) said,

 

"The supplication made by the Companion of the Fish

(Prophet Yunus, Alaihi Salaam) in the belly of the fish was,

 

'La ilaha illa anta, subhanaka, inni kuntu minaz-zalimin'

 

{ There is no God but You; Glory be to You,Truly I have been one of the wrongdoers }

  [Surah al-Anbiyah, 21: 87]

 

If any Muslim supplicates in these words,

his supplication will be accepted."

 

In another report Rasulullah (Sallallaho alaihe wasallam) had said,

 

"I know words that will cause Allah Azza wa Jall to remove one's distress.

These are the words (of supplication) of my brother Yunus, peace be upon him,"
