Narrated Jabir:
حَدَّثَنَا قُتَيْبَةُ ، قَالَ حَدَّثَنَا اللَّيْثُ ، عَنْ أَبِي الزُّبَيْرِ ، عَنْ جَابِرٍ ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ يَدْخُلُ النَّارَ أَحَدٌ مِمَّنْ بَايَعَ تَحْتَ الشَّجَرَةِ " . قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
that the Messenger of Allah (ﷺ) said: "None of those who gave the pledge under the tree shall enter the Fire."
