Nahj al-Balāgha
Hadith 78وفي رواية : وَأيْمُ اللهِ لَتَغْرَقَنَّ بَلْدَتُكُمْ حَتَّى كَأَنِّي أَنْظُرُ إِلى مَسْجِدِهَا كَجُؤْجُؤِ سَفِينَةٍ، أَوْ نَعَامَةٍ جَاثِمَةٍ
Another version : By Allāh, your city would certainly be drowned so much so that as though I see its mosque like the upper part of a boat or a sitting ostrich.
