My father said: I told Ibn 'Abbas and he said: What is so amazing about that? When ʼUmar called the prominent shaikhs among the Companions of Muhammad ﷺ, he would call me with them and say: Do not speak until they have spoken. He called us one day or one night and said: The Messenger of Allah ﷺ said about Lailatal-Qadr what you know, so seek it in the odd numbered nights of the last ten nights; on which odd-numbered night do you think it is?  

وَمَا أَعْجَبَكَ مِنْ ذَلِكَ؟ كَانَ عُمَرُ إذَا دَعَا الْأَشْيَاخَ مِنْ أَصْحَابِ مُحَمَّدٍ ﷺ دَعَانِي مَعَهُمْ فَقَالَ لَا تَتَكَلَّمْ حَتَّى يَتَكَلَّمُوا قَالَ فَدَعَانَا ذَاتَ يَوْمٍ أَوْ ذَاتَ لَيْلَةٍ فَقَالَ إِنَّ رَسُولَ اللهِ ﷺ قَالَ فِي لَيْلَةِ الْقَدْرِ مَا قَدْ عَلِمْتُمْ فَالْتَمِسُوهَا فِي الْعَشْرِ الْأَوَاخِرِ وِتْرًا فَفِي أَيِّ الْوِتْرِ تَرَوْنَهَا؟
