When you are nearing your death – 1

لا إلهَ إلاّ اللّه

Laa ‘ilaaha ‘illallaahu

There is none worthy of worship but Allah.

Al-Bukhari: 3346

When you are nearing your death – 2

أَشْهَدُ أَنْ لَا إِلَهَ إلَّا اللهُ وَحْدَهُ لَا شَرِيكَ لَهُ، وَأَشْهَدُ أَنَّ مُحَمَّداً عَبْدُهُ وَرَسُولُهُ

Ash-hadu ‘an laa ‘ilaaha ‘illallaahu wahdahu laa shareeka lahu wa ‘ash-hadu ‘anna Muhammadan ‘abduhu wa Rasooluhu.

I bear witness that none has the right to be worshipped but Allah alone, Who has no partner; and I bear witness that Muhammad is His slave and His Messenger.

Muslim 1:209
