Surah Yunus, Ayat 38

Ayat 38. Or do they say: "He (Muhammad ) has forged it?" Say: "Bring then a Surah (chapter) like unto it, and call upon whomsoever you can, besides Allah, if you are truthful!" 

Hazrat Abdullah bin `Amr bin Al-`As (May Allah be pleased with them) reported: The Messenger of Allah  [SAWW](PBUH) said, "Convey from me even an Ayah of the Qur'an; relate traditions from Banu Israel, and there is no restriction on that; but he who deliberately forges a lie against me let him have his abode in the Hell.'' [Al-Bukhari Hadith # 3461].  

Lesson : as mentioned above in Surah Yunus Ayat 38. "Or do they say: "He (Muhammad  [SAWW](PBUH) has forged it?"  This Hadith contains the following three important points:

1. It stresses the importance of acquiring knowledge of the Qur'an and Hadith and imparting it to others. No matter whether one has more or less knowledge, he must communicate it to others. There is no justification to presume that preaching or inviting to the Message of Allah is the duty of religious scholars and those who are well-versed in this sphere. In fact, it is a duty upon every Muslim, so much so that if a person knows even a single Verse of the Qur'an, that is to say if he knows only one injunction of Allah, he is duty bound to communicate it to other people.

2. It allows the communication of Jewish Traditions but this permission is subject to the condition that such Traditions are not against the elucidations of the Qur'an and Hadith.

3. There is a stern warning on attributing any false saying to the Prophet  [SAWW](PBUH). This demands strict scrutiny of Ahadith. If a Hadith does not have a reliable authority or whose chain of narrators has a false link or a person of doubtful integrity, that is to say if it is weak, then it is a serious offense to quote it as a Hadith of the Prophet  [SAWW](PBUH).
