Umarah al-Jarmi says: Sayyiduna Ali (may Allah be pleased with him) gave me the choice between my mother and my paternal uncle, and then said about my younger brother: If he too were of this age, I would give him the choice as well.
Imam al-Shafi'i (may Allah have mercy on him) said: Ibrahim narrated from Yunus, from Umarah, from Sayyiduna Ali (may Allah be pleased with him) the like of it, and he said in the hadith: I was seven or eight years old at the time.
