[Machine] Ibn Abbas heard that delaying Isha prayer is recommended and recited {and a portion of the night} [Hud 114].  

البيهقي:٢١٢٢أَخْبَرَنَا أَبُو نَصْرِ بْنُ قَتَادَةَ أنا أَبُو مَنْصُورٍ النَّضْرَوِيُّ ثنا أَحْمَدُ بْنُ نَجْدَةَ ثنا سَعِيدُ بْنُ مَنْصُورٍ ثنا سُفْيَانُ عَنْ عُبَيْدِ اللهِ بْنِ أَبِي يَزِيدَ

سَمِعَ ابْنَ عَبَّاسٍ يُسْتَحَبُّ تَأْخِيرَ الْعِشَاءِ وَيَقْرَأُ {وَزُلَفًا مِّنَ اللَّيْلِ} [هود 114]
