سَعِيدُ بْنُ الْمُسَيِّبِ عَنْ أَبِي وَاقِدٍ
If I were to choose as my bosom friend I would have chosen the son of Abu Quhafa (Abu Bakr) as my bosom friend. (Using translation from Muslim 2383c)
قَالَ رَسُولُ اللهِ ﷺ «لَوْ كُنْتُ مُتَّخِذًا خَلِيلًا لَاتَّخَذْتُ ابْنَ أَبِي قُحَافَةَ خَلِيلًا وَلَكِنَّ صَاحِبَكُمْ خَلِيلُ اللهِ ﷻ»
