"The Messenger of Allah said: 'Allah has taken me as a close friend (Khalil) as He took Ibrahim as a close friend.

"إِن اللهَ اتخذَنِي خلِيلا كمَا اتخذَ إِبْرَاهِيمَ خلِيلا. فمَنزِلِى ومنزلُ إِبراهيمَ في الجنةِ يَوْمَ الْقِيَامَةِ تِجَاهين، والعباس بَينَنَا مُؤمِن بَينَ خَلِيلينِ".

ابن ماجة:١٤١ – حَدَّثَنَا عَبْدُ الْوَهَّابِ بْنُ الضَّحَّاكِ حَدَّثَنَا إِسْمَاعِيلُ بْنُ عَيَّاشٍ عَنْ صَفْوَانَ بْنِ عَمْرٍو عَنْ عَبْدِ الرَّحْمَنِ بْنِ جُبَيْرِ بْنِ نُفَيْرٍ عَنْ كَثِيرِ بْنِ مُرَّةَ الْحَضْرَمِيِّ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرٍو قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ إِنَّ اللَّهَ اتَّخَذَنِي خَلِيلاً كَمَا اتَّخَذَ إِبْرَاهِيمَ خَلِيلاً فَمَنْزِلِي وَمَنْزِلُ إِبْرَاهِيمَ فِي الْجَنَّةِ يَوْمَ الْقِيَامَةِ تِجَاهَيْنِ وَالْعَبَّاسُ بَيْنَنَا مُؤْمِنٌ بَيْنَ خَلِيلَيْنِ
