He told people not to discriminate between the prophets

  Again, in accordance with Allah's command, the Prophet (saas) revealed that we should not discriminate between the prophets sent by Allah, and in one hadith, said, "Don't give superiority to any prophet amongst Allah's prophets."47 All of the prophets were loved and trusted by Allah, and were blessed godly people rewarded with Paradise. All of the prophets taught the religion of Allah, and like the Prophet Muhammad (saas), called all those they could reach to the way of Allah. That is a most important aspect of the actions of the Prophet (saas), a matter which appears in the Qur'an in this form:

Say, "We believe in Allah and what has been sent down to us and what was sent down to Ibrahim, Isma'il and Ishaq and Ya'qub and the Tribes, and what Musa and 'Isa and all the prophets were given by their Lord. We do not differentiate between any of them. We are Muslims submitted to Him." (Surah Al 'Imran: 84)

Say, "We believe in Allah and what has been sent down to us and what was sent down to Ibrahimand Isma'il and Ishaq and Ya'qub and the Tribes, and what Musa and 'Isa were given, and what all the prophets were given by their Lord. We do not differentiate between any of them. We are Muslims submitted to Him." (Surat al-Baqara: 136)
