It is narrated from Hazrat Buraidah (may Allah be pleased with him) that once he was among the 24 companions (may Allah be pleased with them) of the Holy Prophet (peace and blessings be upon him) who were with the Holy Prophet (peace and blessings be upon him). The Holy Prophet (peace and blessings be upon him) was offering prayer near Maqam Ibrahim, and the companions (may Allah be pleased with them) were sitting behind, waiting. After finishing the prayer, the Holy Prophet (peace and blessings be upon him) moved towards the Ka'bah as if trying to catch something. Then he returned, and the companions (may Allah be pleased with them) stood up. The Holy Prophet (peace and blessings be upon him) gestured with his blessed hand for them to sit, so they sat down. The Holy Prophet (peace and blessings be upon him) asked them, "Did you see me, after finishing the prayer, moving towards the Ka'bah as if I was trying to catch something?" They replied, "Yes, O Messenger of Allah!" The Holy Prophet (peace and blessings be upon him) said, "Paradise was presented before me, and I have never seen anything like its blessings. A bunch of grapes passed before me which I liked, so I moved forward to catch it, but it moved ahead of me. If I had caught it, I would have planted it before you so that you could eat the fruits of Paradise. And know that the mushroom is a cure for the eyes, and Ajwa is a fruit of Paradise, and this black seed which is in salt is a cure for every disease except death."
