Or if some RAWI mentions an event...

Or if some RAWI mentions an event, which he did not see himself, and then he does not mention the name of his source, it will be a proof of forgery. These three devices are the most important for sifting the authentic AHADITH form the mass collected in the books of traditions. ADDENDA* THE SATANIC SUGGESTION!!!

It appears from a story narrated by many SUNNI (traditionist) (fortunately this time not in their "Six authentic collections") that even after the supposed repeated removal of the pathetic satanic portion from the Prophet's heart, he fell prey to a very serious satanic suggestion --- and that too in conveying the revelation to the people!

AS-SUYUTI his AD-DURRU 'L-MANTHUR has quoted from ten (traditionists) several "traditions" to this effect, one of which is given here as a sample: - "IBN ABI HATIM has narrated through MUSA IBN 'AQABAH from IBN SHAHAB that he said, "When the SURAH AN-NAJM was revealed; and the polytheists used to say, "If this man (the Prophet) were to mention our deities in good (terms) we would have accepted him and his companions; but he does not use such abusive and harsh words about others like the Jews and the Christians who oppose his religion, as he does about our gods"; and the Messenger of Allah (s.a.w) was much distressed because of the troubles inflicted upon him and his companions by the idolaters and their rejection (of faith), and he was aggrieved by their straying; he therefore wished cessation of their harmful activities.

When Allah sent down the SURAH AN-NAJM, and he recited (the verses 19 and 20): Have you then considered the Lat and the 'USSAH, and MANAT, the third, the other? The Satan inserted some words after the mention of the idols and said, "and surely they are the exalted cranes, and surely it is their intercession that is hoped for".

It was the Satan's rhymed composition and his mischief; and these two sentences entered the heart of every MECCAN polytheist, and it was continuously on their tongues, and they congratulated each other and said that Muhammad had returned to his old religion and that of his people. When the Messenger of Allah (s.a.w) reached the end of (the SURAH) AN-NAJM, he prostrated and with him did prostrate every Muslim and polytheist.

This word spread among the people, and the Satan propagated it, until the news reached the country of Ethiopia.
