(9) باب مِيرَاثِ الْجَدِّ مَعَ الأَبِ وَالإِخْوَةِ
Narrated Ibn `Abbas:
The person about whom Allah's Messenger (ﷺ) said, "If I were to take a Khalil from this nation (my followers), then I would have taken him (i.e., Abu Bakr), but the Islamic Brotherhood is better (or said: good)," regarded a grandfather as the father himself (in inheritance).
