Ibn Abbas on Dhikr: Remembrance of Allah is the greatest deed

‘Antarah reported: I asked Ibn Abbas, may Allah be pleased with him, “Which deed is best?” Ibn Abbas said, “The remembrance of Allah is greatest, (29:45). No people sit in a house, in which they are occupied with the Book of Allah among them and they study it together, except that the angels will shade them in their wings. They will be the guests of Allah as long as they remain there, until they enter into another conversation.”

عَنْ عَنْتَرَة قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ رَضِيَ اللهُ عَنْهُ أَيُّ الْعَمَلِ أَفْضَلُ قَالَ ذِكْرُ اللَّهِ أَكْبَرُ وَمَا جَلَسَ قَوْمٌ فِي بَيْتٍ يَتَعَاطَوْنَ فِيهِ كِتَابَ اللَّهِ فِيمَا بَيْنَهُمْ وَيَتَدَارَسُونَهُ إِلَّا أَظَلَّتْهُمُ الْمَلَائِكَةُ بِأَجْنِحَتِهَا وَكَانُوا أَضْيَافَ اللَّهِ مَا دَامُوا فِيهِ حَتَّى يَخُوضُوا فِي حَدِيثٍ غَيْرِهِ
