Abdullah ibn Mas’ud reported: The Prophet, peace and blessings be upon him, drew a square and in the middle he drew a line which poked out the end. Across the middle line he drew some smaller lines. The Prophet said, “This is man and the square surrounding him is death. The middle line is his worldly hopes and the smaller lines are his troubles. If this one misses him, another will distress him. If that one misses him, another will distress him.”

عَنْ عَبْدِ اللَّهِ رَضِيَ اللَّهُ عَنْهُ قَالَ خَطَّ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَطًّا مُرَبَّعًا وَخَطَّ خَطًّا فِي الْوَسَطِ خَارِجًا مِنْهُ وَخَطَّ خُطَطًا صِغَارًا إِلَى هَذَا الَّذِي فِي الْوَسَطِ مِنْ جَانِبِهِ الَّذِي فِي الْوَسَطِ وَقَالَ هَذَا الْإِنْسَانُ وَهَذَا أَجَلُهُ مُحِيطٌ بِهِ أَوْ قَدْ أَحَاطَ بِهِ وَهَذَا الَّذِي هُوَ خَارِجٌ أَمَلُهُ وَهَذِهِ الْخُطَطُ الصِّغَارُ الْأَعْرَاضُ فَإِنْ أَخْطَأَهُ هَذَا نَهَشَهُ هَذَا وَإِنْ أَخْطَأَهُ هَذَا نَهَشَهُ هَذَا
