Vicissitudes of time
Nahj al-Balāgha|Volume 1|Book 1|Chapter 187
إِنَّمَا مَثَلي بَيْنَكُمْ مَثَلُ السِّرَاجِ فِي الظُّلْمَةِ، يَسْتَضِيءُ بِهِ مَنْ وَلَجَهَا. فَاسْمَعَوا أَيُّهَا النَّاسُ وَعُوا، وَأَحْضِروا آذَانَ قُلُوبِكُمْ تَفْهَمُوا.
I am among you like a lamp in the darkness. Whoever enters by it will be lit from it. So listen O men, preserve it and remain attentive with the ears of your hearts so that you may understand.
