حَدَّثَنَا سَعِيدُ بْنُ أَبِي مَرْيَمَ، قَالَ: أَخْبَرَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، قَالَ: حَدَّثَنَا زَيْدُ بْنُ أَسْلَمَ، عَنْ أَبِيهِ، عَنْ عُمَرَ بْنِ الْخَطَّابِ قَالَ: لاَ يَكُنْ حُبُّكَ كَلَفًا، وَلاَ بُغْضُكَ تَلَفًا، فَقُلْتُ: كَيْفَ ذَاكَ؟ قَالَ: إِذَا أَحْبَبْتَ كَلِفْتَ كَلَفَ الصَّبِيِّ، وَإِذَا أَبْغَضْتَ أَحْبَبْتَ لِصَاحِبِكَ التَّلَف.
It is narrated from Sayyiduna Umar bin Khattab (may Allah be pleased with him), he said: Let not your love make you insane, and let not your enmity incite you to destruction. I asked: How is that? He said: That when you love, you love like a child, madly, considering everything to be for him alone; and when you bear enmity, you wish that the one you hate be destroyed altogether.
