If anyone recites ‘Allahumma inni as’aluka al-jannah’ (O Allah, I ask You for Paradise), Jannah itself will pray to Allah to admit the person to Jannah.
Allah (swt) is so merciful towards his servants that he has taught us the dua which can lead us to Jannah.
It was narrated that Anas (may Allah be pleased with him) said: The Prophet (peace and blessings of Allah be upon him) said: “Whoever asks Allah for Paradise three times, Paradise will say, ‘O Allah, admit him to Paradise.’ Whoever seeks protection from the Fire three times, Hell will say, ‘O Allah, protect him from the Fire.’”
