Imam Ali (AS) said, 'So be conscious of your duty to Allah, O servants of Allah, with the caution of a wise man whose heart is preoccupied with reflection [about the Hereafter], whose body the fear [of Allah] has afflicted with pain, and whose engagement in the night prayer has turned his already short sleep into wakefulness.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ): فاتَّقُوا اللّهَ عِبادَ اللّهِ تَقِيَّةَ ذِي لُبٍّ ، شَغَلَ التَّفَكُّرُ قَلبَهُ ، وأنصَبَ الخَوفُ بَدَنَهُ ، وأسهَرَ التَّهَجُّدُ غِرارَ نَومِهِ .
