I had two threads with me last night, one white and one black. I looked at this one and then at this one." The Messenger of Allah ﷺ smiled and said, "The white thread is from the black thread that is in the horizon of the sky."
قُلْتُ يَا رَسُولَ اللهِ قَدْ حَفِظْتُ كُلَّ شَيْءٍ أَوْصَيْتَنِي بِهِ غَيْرَ الْخَيْطِ الْأَبْيَضِ مِنَ الْخَيْطِ الْأَسْوَدِ إِنِّي نِمْتُ الْبَارِحَةَ مَعِي خَيْطانِ أنْظُرُ إِلَى هَذَا مَرَّةً وَإلَى هَذَا مَرَّةً فَتَبَسَّمَ رَسُولُ اللهِ ﷺ وَقَالَ «إِنَّمَا الْخَيْطُ الْأَبْيَضُ مِنَ الْخَيْطِ الْأَسْوَدِ الَّذِي فِي أُفُقِ السَّمَاءِ»
