Mus'ab al-Makki narrates: I met Sayyiduna Anas bin Malik (may Allah be pleased with him), Sayyiduna Zayd bin Arqam (may Allah be pleased with him) and Sayyiduna al-Mughirah bin Shu'bah (may Allah be pleased with him), and I heard them relate that the Prophet (peace and blessings be upon him) said: "On the night of the cave, Allah Almighty commanded a tree, and it sprang up in front of the Prophet (peace and blessings be upon him) and concealed him. Allah Almighty commanded the spider, and it wove a web in front of the Prophet (peace and blessings be upon him) and concealed him. Allah Almighty commanded two wild doves, and they settled at the mouth of the cave. Young men of Quraysh, from every clan, came with their sticks, their clubs and their swords, until, when they were at a distance of forty cubits from the Prophet (peace and blessings be upon him), one of them hurried ahead and looked into the cave; he saw two doves at the mouth of the cave. He went back to his companions, and his companions asked: What is the matter? He replied: I have seen two doves at the mouth of the cave, from which I knew that there is no one here. The Prophet (peace and blessings be upon him) heard what he said and knew that Allah Almighty had turned them away from him by means of those doves. So the Prophet (peace and blessings be upon him) prayed for them (the doves), invoked blessing upon them, prescribed a compensation for them, and they were settled in the Haram."
Al-Tabarani recorded it in al-Mu'jam al-Kabir. As for the narrator Mus'ab al-Makki and the one who narrates from him, namely Uwayn bin Amr al-Qaysi, I have not found anyone who gives an account of either of them. The rest of its narrators are thiqat (trustworthy).
