For children, - Islamic Jokes: Holy Prophet Muhammed (saw) and Old Woman(Islamic Humour)

Holy Prophet Muhammed (saw) smiled often and would make jokes with
members of his community. For example, An old woman came to our Holy
Prophet Muhammed (saw) and said: "O Messenger of Allah, pray to Allah
(Subhanahu Wa Ta'ala) that I will enter Paradise." Holy Prophet
Muhammed (saw) said jokingly, "O Mother of so-and-so, no old women
will enter Paradise." The old woman went away crying, after hearing
from Holy Prophet Muhammed (saw). Then Holy Prophet Muhammed (saw)
sent one of his companions to tell her that, she will enter Paradise
by becoming a young lady, because the Paradise is for only young
people.
Holy Prophet Muhammed (saw) said: "Do not laugh too much, for laughing
too much deadens the heart." At another place, Holy Prophet Muhammed
(saw) said: "If you knew what I know, you would laugh little and weep
much."
Imam Jafar as Sadiq (AS)said: Avoid incorrect jokes and humors, as it
is the cause of enmity and grudge. Also Imam Jafar as Sadiq (AS) said:
The believers laughter should be only a smile. At another place Imam
Jafar as Sadiq (AS) said: Beware of joking, because it causes rancor
and drives into malice. Joking is the lesser revilement.
Making Fun of People just for the sake of Laugh
Holy Prophet Muhammed (saw) said, "Woe to whoever lies while quoting
someone so that others laugh. Woe to him!"
Imam Jafar as Sadiq (as) said, Do not make fun of people since it will
ruin one's honor and dignity. The Prophet's companions used to gather
together and tell jokes until the following verse was revealed: "Has
not the Time arrived for the Believers that their hearts in all
humility should engage in the remembrance of Allah ..." (Noble Qur'an,
57:16) Then after Holy Prophet Muhammed (saw) recited this verse they
stopped their joking and vain talk.
