Tahdhīb al-Aḥkām|Volume 2|Book 1|Chapter 4
وَبِهَذَا اَلْإِسْنَادِ عَنِ اَلْحَسَنِ بْنِ عَلِيٍّ عَنْ إِسْحَاقَ اَلْبَطِيحِيِّ قَالَ: رَأَيْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ صَلَّى اَلْعِشَاءَ اَلْآخِرَةَ قَبْلَ سُقُوطِ اَلشَّفَقِ ثُمَّ اِرْتَحَلَ
And with this chain from al-Hasan ibn Ali from Ishaq al-Batihi, who said:
I saw Abu Abdillah عليه السلام perform the ‘Ishaʾ al-Akhirah (the last evening prayer) before the disappearance of the shafaq (redness), then He عليه السلام departed.
