Musnad Ahmad Hadith 22972

It is narrated from 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 (ﷺ) who were with the Holy Prophet (ﷺ). The Holy Prophet (ﷺ) 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 (ﷺ) 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 (ﷺ) gestured with his blessed hand for them to sit, so they sat down. The Holy Prophet (ﷺ) 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 (ﷺ) 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."
