My father, Allah may have mercy upon him, narrated to us from Sa’d bin Abdullah from Ahmed bin al-Hasan bin Ali bin Faddhal from … Ammar bin Musa that Abu Abdullah عليه السلام was asked whether the inhabitants of the heavens can see the inhabitants of the earth. He عليه السلام answered: The inhabitants of the heavens can see only the believers, because they give light like the light of the stars. Some asked: Can they see the people on this earth markedly? He عليه السلام answered: No, they cannot. They can only see their lights wherever they go. He عليه السلام then added: On the Day of Resurrection, every believer will be given five hours during which he will be granted the right of intercession.
