Murrah al-Hamdani, may Allah have mercy on him, began to weep, so it was said to him: What has made you weep? He said: I fear that Allah, the Mighty and Majestic, will become displeased with us, because I hear the statement of Allah, the Mighty and Majestic: ﴿إِنَّالَّذِينَفَرَّقُوادِينَهُمْوَكَانُواشِيَعًالَسْتَمِنْهُمْفِيشَيْءٍ﴾ "Indeed, those who have divided their religion and become sects, you have nothing to do with them," and I fear that Allah, the Mighty and Majestic, will have nothing to do with us.
