Abu Burdah said: I met Marwan bin Al-Hakam in Madinah, and he said: O son of our master Abu Musa Al-Ash'ari (may Allah be pleased with him)! Shall I not inform you that, according to you, the grandfather does not take the place of the father, and you do not refute this? Abu Burdah said: I replied: You also do not do so. Marwan replied: I bear witness that our master Uthman (may Allah be pleased with him) testified that our master Abu Bakr (may Allah be pleased with him) considered the grandfather in the place of the father in the absence of the father.
