Translation of the verse 86 from Surah sad : Number of verses 88 - - page 458 - Part 23.

Every child of Makkah was a witness that Muhammad (upon whom be Allah's peace) was not an impostor. Never had anybody from among the people of Makkah ever heard anything from him, which might have caused somebody the doubt that he aspired to be a great man and was planning and scheming for that end.
