Allah Almighty states in the Holy Quran:

یٰۤاَیُّهَا  الَّذِیْنَ  اٰمَنُوا  اتَّقُوا  اللّٰهَ  حَقَّ  تُقٰتِهٖ  وَ  لَا  تَمُوْتُنَّ  اِلَّا  وَ  اَنْتُمْ  مُّسْلِمُوْنَ(۱۰۲)

O believers! Fear Allah as He should be rightfully feared, and never die but as Muslims.

[Kanz-ul-Iman (translation of Quran)] (Part 04, Surah Aal-e-Imraan, Verse 102)

Under this verse, it is stated in Tafsir Noor-ul-‘Irfan, ‘This implies that the determining factor is to pass away on Islam. If one remains a believer throughout his life, and becomes a non-Muslim at the time of death, then he is like an actual non-Muslim.’

Under another verse of a similar meaning, the honourable Mufti writes the following, ‘We come to know that accomplishment does not lie in being a Muslim, but to die as a Muslim. May Allah Almighty grant us all death upon faith, آمین.’ (Part 1, Surah Al-Baqarah, under the verse 132)

The seal of Prophets صَلَّى الـلّٰـهُ عَلَيْهِ وَاٰلِهٖ وَسَلَّم has stated: ‘اِنَّمَا الْاَعْمَالُ بِالْخَوَاتِیْمِ’ i.e. deeds are dependent upon the end. (Bukhari, vol. 4, p. 274, Hadith 660)  

May Allah Almighty raise us with our faith intact and resurrect us among the righteous.

اٰمِیْن بِجَاہِ النَّبِیِّ الْاَمِیْن صلَّی اللہ علیہ واٰلہٖ وسلَّم

Lest an action that displeases Allah is performed

Sayyiduna Imam Hasan Al-Basri رَحْمَةُ الـلّٰـهِ عَلَيْه was asked, ‘What is your state?’

He رَحْمَةُ الـلّٰـهِ عَلَيْه responded, ‘What would be the state of a person whose boat breaks in the middle of a sea, scattering its planks in every direction and every person is seen drowning on those planks?’
