بسم الله الر حمن الرحيم
Imam Muhammad ibn Ali al-Baqir (a.s.) narrates:
Janabe Safiyah ibn Abdul Muttaleb’s son expired and at that time Umar ibn Khattab said, “Surely your relation with Muhammad (Holy Prophet s.a.w.a.s.) will not benefit you.
Safiyah then went to Holy Prophet (s.a.w.a.s.) and she informed him about what Umar had said.
Holy Prophet (s.a.w.a.s.) came out of his house and announced congregational prayers (namaz-e-jamaat) after which the people gathered.
Holy Prophet (s.a.w.a.s.) said: Why is that some of you think that nearness to me will not benefit? If I were to stand at Maqam-al-Mahmood I will certainly do shifa in your illness. Today if anyone were to ask me about his father, I will most certainly give him the details.
One person from the crowd stood up and asked Holy Prophet (s.a.w.a.s.), “Who is my father?”
He (s.a.w.a.s.) replied, “Your father is other than whom you are calling. Your father is so and so.”
Another person asked, “Who is my father?” He (s.a.w.a.s.) replied, “The one whom you consider.”
The Holy Prophet (s.a.w.a.s.) then said, “Why is the one who feels that nearness to me will not benefit, stand up and ask me?”
Umar stood up and said, “I seek protection of Allah. Forgive me and Allah will forgive you.
On this occasion verse 101 of Surah Maidah was revealed.
