وَعَن معَاذ
أَنَّهُ سَأَلَ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَنْ أَفْضَلِ الْإِيمَانِ قَالَ: «أَنْ تُحِبَّ لِلَّهِ وَتُبْغِضَ لِلَّهِ وَتُعْمِلَ لِسَانَكَ فِي ذِكْرِ اللَّهِ قَالَ وماذا يَا رَسُول الله قَالَ: وَأَن تحب للنَّاس مَا تحب لنَفسك وَتَكْرَهُ لَهُمْ مَا تَكْرَهُ لِنَفْسِكَ»
He also said that he asked the Prophet (sallallahu alayhi wa sallam) what was the most excellent aspect of faith, and received the reply, “That you should love for God’s sake, hate for God’s sake, and employ your tongue in making mention of God.” “What more, messenger of God?” he asked and was told, “That you should like other people to have what you like yourself, and dislike that they should have what you dislike yourself.”
