Goodwill towards others is part of faith

عَنْ أَنَسٍ، عَنِ النَّبِيِّ صلّى الله عليه وسلّم قَالَ ‏ “‏ لا يُؤْمِنُ أَحَدُكُمْ حَتَّى يُحِبَّ لأَخِيهِ مَا يُحِبُّ لِنَفْسِهِ

Hazrat Anas^ra narrated that the Holy Prophet^sa said, “None of you can be a true believer until he desires for his brother what he desires for himself.

(Sahih al-Bukhari, Kitab al-iman, Bab mina l-imani ’an yuhibba li akhihi ma yuhibbu li nafsih, Hadith 13)
