Muhammad bin Sirin, may Allah have mercy on him, said: I said to Ubaidah, "Tell me about the grandfather." He replied, "I remember eighty different issues regarding the grandfather."

Abdullah bin Amr Kharfi said: A man came to Sayyiduna Ali (may Allah be pleased with him) and asked about (the obligation of) inheritance, so he said: If there is no mention of the grandfather in it, then ask.

A man from Murad heard Sayyiduna Ali, may Allah be pleased with him, saying: Whoever likes to let the germs of Hell enter him, let him give a verdict in the matter of grandfather and brothers.
