April Fools
Question

In some foreign countries – kafir (non-Muslim) countries – there is the well-known custom of April Fools, which happens on the first day of April. Some Muslims are imitating them in this, thinking that it is permissible to tell lies on this day… what is your opinion on this belief and on this custom?
Praise be to Allah.Lying is not permissible at all, at any time. And it is not permissible to imitate the kuffar (non-Muslims) and to be like them, on this day or on any other, because the Prophet (peace and blessings of Allah be upon him) said: “Whoever imitates a people is one of them.”  
And Allah knows best.
