In The Name of Allah, The Most Merciful, The Bestower of Mercy.

Aa’ishah, may Allah be pleased with her, narrated:

“There was no traite more hated to Allah’s Messenger, peace and blessings of Allah be upon him, than lying. A man would speak based on lies in the presence of the Prophet, peace and blessings of Allah be upon him, and he would not be content until he knew that he had repented.” [Sahih Tirmidhi 1973]

Imam An-Nawawi, may Allah have mercy upon him, said:

The texts of the Qur’an and Sunnah are abundant regarding the general prohibition of lying. It is one of the repugnant sins and immoral flaws. The consensus of the Ummah (the Scholars) is firmly established regarding its prohibition alongside the abundant texts (on the subject matter). [Al-Ad’kar 377]
