'Ali observed: By Him Who split up the seed and created something living, the Apostle (may peace and blessings be upon him) gave me a promise that no one but a believer would love me, and none but a hypocrite would nurse grudge against me. (Using translation from Muslim 78)
«وَالَّذِي فَلَقَ الْحَبَّةَ وَبَرَأَ النَّسَمَةَ إِنَّهُ لَعَهْدُ النَّبِيِّ الْأُمِّيِّ إِلَيَّ أَنْ لَا يُحِبَّنِي إِلَّا مُؤْمِنٌ وَلَا يَبْغَضَنِي إِلَّا مُنَافِقٌ»
