O Allah! Make us die as Muslims!

Quran 2:132- Ya'qoob said "O my sons! Allah has chosen for you the (true) religion, then DIE NOT EXCEPT AS MUSLIMS."

Remember to make this du'a every day:

رَبَّنَآ أَفۡرِغۡ عَلَيۡنَا صَبۡرً۬ا وَتَوَفَّنَا مُسۡلِمِين

Quran 7:126-"Our Lord! pour out on us patience, and cause us to die as Muslims."

Prophet (SAW) said, "He whose last words are: 'La ilaaha illallaah' (There is no true god worthy of worship except Allah) will enter Jannah (paradise)."
[Sunan Abu Dawud]

Prophet (SAW) said that Allah will save a man of his community the record of whose sins fills 99 books, each book extending as far as the eye can see. Against all this will be weighed the one good deed that he has, which is his witnessing that "There is no god but Allah and that Muhammad is His Messenger", and it will outweigh all the rest. The Prophet (S) then said: "Nothing is of any weight with Allah's Name."
[Tirmidhi, hasan gharib]
