April fool day vs real muslims!

Lying is an evil characteristic, which all religions and systems of ethics warn against and which man's innate common sense (fitrah) agrees that it is wrong.

Our purely monotheistic sharee’ah warns against lying in the Qur’aan and Sunnah, and there is consensus that it is haraam. The liar will have bad consequences in this world and in the next.
According to sharee’ah, lying is not permitted except in specific cases which do not lead to loss of rights, bloodshed or slander of people’s honour, etc., but which concern saving lives, reconciling between people, or creating love between husband and wife.

Allaah says (interpretation of the meaning):
“It is only those who believe not in the Ayaat (proofs, evidences, verses, lessons, signs, revelations, etc.) of Allaah, who fabricate falsehood, and it is they who are liars
[al-Nahl 16:105]

It was narrated from Abu Hurayrah that the Prophet(peace and blessings of Allaah be upon him) said: “The signs of the hypocrite are three: when he speaks, he lies; when he makes a promise, he breaks it; and when he is entrusted with something, he betrays that trust.”
(Narrated by al-Bukhaari, 33; Muslim, 59)

It is even prohibited to lie to a small kid according to shareea
‘Aamir (may Allaah be pleased with him) said: “My mother called me one day when the Messenger of Allaah (peace and blessings of Allaah be upon him) was sitting in our house. She said, ‘Come here, and I will give you (something).’ The Messenger of Allaah (peace and blessings of Allaah be upon him) said, ‘What do you want to give him?’ She said, ‘I will give him a date.’ The Messenger of Allaah(peace and blessings of Allaah be upon him) said: ‘If you had not given him something, you would have been lying.’”

And it was narrated that Abu Hurayrah (may Allaah be pleased with him) said: “The Messenger of Allaah (peace and blessings of Allaah be upon him) said: ‘Whoever says to a child, ‘Come here and take this,’ then does not give him something, this is counted as a lie.’”
(Narrated by Abu Dawood, 4991)

It was narrated that Hafs ibn ‘Aasim said: “The Messenger of Allaah(peace and blessings of Allaah be upon him) said: ‘It is sufficient lying for a man to speak of everything that he hears.’”
(Narrated by Muslim, 5) 

It was narrated that Mu’aawiyah ibn Haydah said: “I heard the Prophet (peace and blessings of Allaah be upon him) say: ‘Woe to the one who talks to make the people laugh and tells lies, woe to him, woe to him.’”
(narrated by al-Tirmidhi, 235. He said: this is a hasan hadeeth. Also narrated by Abu Dawood, 4990).
