The Prophet (peace be upon him) said, "Whoever recites this Du'a three times, Jannah will say for him/ her, "O Allah, let him/her enter Jannah "
Tirmidhi
Yes, this Hadith is a beautiful reminder of the power of sincere supplication (du'a) in Islam. The Prophet Muhammad (peace be upon him) said:
"Whoever recites this du'a three times, Paradise (Jannah) will say, 'O Allah, admit him into Paradise.'"
The du'a being referred to in this context is:
اللّهُمَّ أَجِرْنِي مِنَ النَّارِ "O Allah, save me from the Fire (of Hell)."
This narration is found in Sunan al-Tirmidhi and emphasizes the importance of constantly seeking Allah's protection from Hellfire and striving for entry into Jannah (Paradise).
May Allah grant us the ability to make this du'a often and bless us all with Jannah, Ameen.
