She said it in a clear voice.

This is a true story that happened in Egypt:

A young man flagged down a taxi in order to take his ill mother to the hospital. They both got in and the driver made his way to the hospital. However, on the way, the son asked for the taxi to be stopped so that he could get out and quickly get some medication for his mother. As he was away, the mother’s health suddenly plummeted and subhan’Allah, the driver noticed the signs of death on her. He immediately went to her side and guided her through the Shahadah (testimony of faith), in accordance to the hadith: “Whoever’s last words are la ilaha illa’Allah (there is no God but Allah), will enter Paradise.” [Abu Dawud]. The mother looked at the driver acknowledging it, and finally she uttered the words of faith before breathing her very last.

When the son returned, the driver informed him of the news. The son went into a natural hysteria whereupon the driver consoled him saying, “Don’t worry, I helped her utter the Shahadah and she said it in a clear voice.” The son then exclaimed, “What! Why did you do that? Don’t you know we are Christians?!” 

Subhan’Allah, the wonders of the Qadr (Decree) of Allah. You just don’t know where it will take you and what your last words/deeds will be. This was a Coptic Christian mother in the throes of death and Allah saved her just in time. May Allah grant us all a good end, ameen.

At the time of death your tongue will speak only what is in the heart.To say La Ilaha Illallah, you must live it.

The Messenger (sallallahu `alayhi wa sallam) said: “Iman is to believe in Allah, His Angels, His Books, His Messengers, the Last Day and the Decree; the good thereof and the bad.” [Muslim]
