وَعَن النُّعْمَان بن بشير
قَالَ: أَنَا أَعْلَمُ بِوَقْتِ هَذِهِ الصَّلَاةِ صَلَاةِ الْعِشَاءِ الْآخِرَةِ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يُصَلِّيهَا لِسُقُوطِ الْقَمَرِ لِثَالِثَةٍ
“I am the one who is best informed of the time of this prayer, the last prayer of the evening. God’s Messenger used to observe it when the moon went down on its third night.”
