It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) entered ihram after one of the two evening prayers (that is, Maghrib or Isha).
Imam al-Tabarani (may Allah have mercy on him) said: "No one narrated this hadith from Qatadah except Hisham al-Dastuwa'i, and his son Mu'adh is alone in narrating it from him."
