Jundub (may Allah be pleased with him) reported: I heard the Prophet (may Allah's peace and blessings be upon him) five (nights) before he died, say: "I stand acquitted before Allah that I should take anyone of you as an intimate friend, for Allah has taken me as an intimate friend just as he took Abraham as an intimate friend. Had I taken anyone from my Ummah as an intimate friend, I would have taken Abu Bakr as an intimate friend. Beware! Those who were before you used to take the graves of their prophets as places for prayer. Beware! Do not take graves as places for prayer, for I forbid you to do so."

Anas ibn Mālik (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "There is no transitive disease and no evil omen, and I like a good omen." It was said: What is a good omen? He said: "A good word."

Zayd ibn Khālid al-Juhani (may Allah be pleased with him) reported: The Messenger of Allah (may Allah’s peace and blessings be upon him) led us in the Fajr prayer at Al-Hudaybiyah after rainfall during the night. At the conclusion of the prayer, he turned toward the people and said: "Do you know what your Lord has said?" They replied: "Allah and His Messenger know best." He said: "He has said: 'Some of My servants have entered the morning as believers in Me and some as disbelievers. He who says, 'We have had rainfall by the grace and mercy of Allah' believes in Me and disbelieves in the stars, and he who says, 'We have had rainfall by the rising of such and such star' disbelieves in Me and believes in the stars.'"

‘Uqbah ibn ‘Āmir al-Juhani (may Allah be pleased with him) reported: A group of people came to the Messenger of Allah (may Allah's peace and blessings be upon him). He accepted the pledge of allegiance of nine and did not accept it from one. They said: O Messenger of Allah, you accepted the pledge of nine but not of this one. He said: "He is wearing an amulet." So, he put his hand in and cut it, and thus, accepted his pledge and said: "Whoever hangs an amulet has committed Shirk (polytheism)."

‘Abdullāh ibn Mas‘ūd (may Allah be pleased with him) reported: I heard the Messenger of Allah (may Allah's peace and blessings be upon him) say: "Incantations, amulets, and love-potions are Shirk (polytheism)."

Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported: I went to the Messenger of Allah (may Allah's peace and blessings be upon him) along with a group of Ash‘ari people, asking him for mounts. He said: "By Allah, I will not give you anything to ride, and I have nothing to mount you on." We stayed there as long as Allah wished. Then some camels were brought to him, and he ordered that we be given three camels. When we set out, some of us said to others: "Allah will not bless us, as we all went to the Messenger of Allah (may Allah's peace and blessings be upon him) asking him for mounts, and although he had sworn that he would not give us mounts, he did give us." Abu Mūsa said: We went to the Prophet (may Allah's peace and blessings be upon him) and mentioned that to him. He said: "I have not provided you with mounts, but Allah has. By Allah, Allah Willing, if I ever take an oath and then see that another option is better than the first, I will make expiation for my oath and do what is better."
