( أَوَلَمْ يَتَفَكَّرُوا ) (Then do they not give thought?): The Quran has given the intellect its due position, saying: (Then do they not give thought?) by encouraging all the mankind to reflect on the matter of Messenger (saws) to know that he is not a madman, taking into consideration that an insane person is someone who cannot choose between alternatives and lacks rational judgment. The clear fact is that the Prophet (saws) came as a warner to all people, warning them of severe punishment, and giving them the glad tidings of Allah’s (swt) Mercy and the entry into Paradise if they follow, repent, seek forgiveness, and return to Allah (swt).
