أَنَا أَعْلَمُ النَّاسِ بِمِيقَاتِ هَذِهِ الصَّلاَةِ عِشَاءِ الآخِرَةِ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّيهَا لِسُقُوطِ الْقَمَرِ لِثَالِثَةٍ  

"By Allah, I am the most knowledgeable of people about the time of the 'Isha' prayers. The Prophet ﷺ used to pray it when the moon set on the third night of the month."  

وَاللَّهِ إِنِّي لأَعْلَمُ النَّاسِ بِوَقْتِ هَذِهِ الصَّلاَةِ صَلاَةِ الْعِشَاءِ الآخِرَةِ كَانَ رَسُولُ اللَّهِ ﷺ يُصَلِّيهَا لِسُقُوطِ الْقَمَرِ لِثَالِثَةٍ
