سورة الرحمن

Ibn Abbas (may Allah have mercy on him): یَخْرُجُ مِنْهُمَا [There come forth from them] means from the water of the sky and the water of the sea, for when drops fall from the sky into the sea, the shells open their mouths and the pearl is formed from those drops.

Imam Ali (peace be upon him): يَخْرُجُ مِنْهُمَا اللُّؤْلُؤُ وَ الْمَرْجانُ [There come forth from them pearls, both large and small]; that is, from the water of the sky and the water of the sea. When the rain falls, the oysters open their mouths in the sea and the rainwater enters into them; then the small pearl comes forth from the small drop and the large pearl comes forth from the large drop.

The Prophet (peace be upon him and his family): اللُّؤْلُؤُ [the pearl] is Hasan (peace be upon him) and المَرْجَانُ [the coral] is Husayn (peace be upon him), because the grains of pearl are larger than the grains of coral.

The Prophet (peace be upon him and his family): The meaning of "those two" is Fatimah (peace be upon her) and Ali (peace be upon him), and the meaning of the pearl and coral in the verse: يَخْرُجُ مِنْهُمَا اللُّؤْلُؤُ وَ الْمَرْجانُ [There come forth from them pearls, both large and small] is Hasan (peace be upon him) and Husayn (peace be upon him).

Imam Sadiq (peace be upon him): يَخْرُجُ مِنْهُمَا اللُّؤْلُؤُ وَ الْمَرْجانُ [There come forth from them pearls, both large and small] — the meaning is Hasan (peace be upon him) and Husayn (peace be upon him).

Imam Rida (peace be upon him): Ali ibn Fudayl said: I asked Imam Rida (peace be upon him) about the saying of Allah, Blessed and Exalted: يَخْرُجُ مِنْهُمَا اللُّؤْلُؤُ وَ الْمَرْجانُ [There come forth from them pearls, both large and small]. He said: "[The meaning is] Hasan (peace be upon him) and Husayn (peace be upon him) and the descendants of those two."
