Fiqh al-Hadith: ➊ Only authentic (sahih) narrations should be cited as evidence. ➋ It is not permissible to mention weak (da'if) and rejected (mardud) narrations. ➌ The principle for living one's life should be that a person always acts with caution and investigation; it should not be that, like the Punjabi proverb "lai lag," he runs after every hearsay and then falls into the pit of destruction. ➍ Hadith is a proof.

Muhammad bin 'Abd Allah ibn Numayr narrated to us, my father narrated to us, Sa’īd bin Ubayd narrated to us, Alī bin Rabī’ah narrated to us, he said: ‘I arrived at the Masjid and al-Mughīrah, the Amīr of al-Kūfah said: ‘I heard the Messenger of Allah, peace and blessings of Allah upon him, saying, ‘Indeed a lie upon me is not like a lie upon anyone else, for whoever lies upon me intentionally, then he shall take his seat in the Fire’.’

Hadith Commentary:Benefits and Issues: Whatever is attributed to the Prophet (sallallahu alayhi wa sallam) becomes part of the religion and Shariah. However, the statement of anyone else does not become religion or Shariah. Therefore, attributing something to the Prophet (sallallahu alayhi wa sallam) is not so light and easy as it is to attribute something to someone else. There is not as much danger and fear in attributing a statement to someone else as there can be—and indeed should be—when attributing something to the Prophet (sallallahu alayhi wa sallam).

Narrated Abu Hurairah: The Prophet ﷺ said: It is enough falsehood for a man to relate everything he hears. Abu Dawud said: Hafs did not mention Abu Hurairah (in his version). Abu Dawud said: No other transmitter except this old man, that is, Ali bin Hafs al-Mada'ini related the perfect chain of this tradition.
