The teacher has good intention but rather a wrong start. According to him, it is
Hadith: that one whose last words are"There is no God, except Allah" enters paradize.
I just take on this. People start accusing me that I am Hadith rejecter but what should
I do with Quran. It is ABSOLUTELY, no true if screened through Quran.
Faroon said the same words. There is no acceptance of repentance at the time
of death. These are all fantasies of the weak people created to console themselves.
The rules n regulations are very severe in Quran. Only those will be survived
who spend all their lives as per guidance of Allah and died as "Muslaymeen".
Rest what the teacher was saying about not using the bad and filthy
words, he may have quoted from Quran, "Say nice words", do not
"defame each other" etc. etc. Anyhow Allah bless him for inspiring the
people to desist from using bad words.
