‘Abdullah ibn Mas‘ūd (may Allah be pleased with him) reported: I asked the Prophet (may Allah's peace and blessings be upon him): "Which sin is the gravest in the sight of Allah?" He said: "To set an equal to Allah while He created you." I said: "This is, indeed, grave." I said: "What comes next?" He said: "To you kill your child lest he should share your food with you." I said: "What comes next?" He said: "To commit adultery with your neighbor's wife."

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Allah Almighty said: 'I am the One Who is most free from want of partners. So, he who does something for the sake of someone else beside Me, I discard him and his polytheism.'"

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Everyone of my Ummah will enter Paradise except those who refuse." They said: "And who would refuse, O Messenger of Allah?" He said: "He who obeys me will enter Paradise, and who disobeys me has refused."

‘Umar ibn al-Khattāb (may Allah be pleased with him) reported: I heard the Prophet (may Allah’s peace and blessings be upon him) say: "Do not exaggerate in praising me as the Christians exaggerated in praising the son of Mary, for I am only His slave. So, call me the slave of Allah and His Messenger."

Anas (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) said: "None of you truly believes until I become dearer to him than his father, his children, and all people."

Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Leave me as I leave you. Verily, what destroyed those before you was their asking questions and their disagreement with their prophets. So, if I forbid you from something, avoid it; and if I command you with something, do as much of it as you can."

‘Abdullāh ibn ‘Amr (may Allah be pleased with him) reported: The Prophet (may Allah's peace and blessings be upon him) said: "Convey from me even if one verse, and narrate from the Children of Israel, and there is no sin in doing that. And whoever intentionally tells a lie about me, let him occupy his seat in Hellfire."

Al-Miqdām ibn Ma‘dikarib (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Lo! Soon a Hadīth from me will be conveyed to a man, while he is reclining on his couch, and he says: ‘Between us and you is Allah’s Book. So, whatever we find in it that is lawful, we consider lawful, and whatever we find in it that is unlawful, we consider unlawful.’ Indeed, whatever the Messenger of Allah made unlawful, it is the same as what Allah made unlawful."

‘Ā’ishah and ‘Abdullāh ibn ‘Abbās (may Allah be pleased with both of them) reported: As the Messenger of Allah (may Allah's peace and blessings be upon him) was about to breathe his last breath, he kept drawing his sheet over his face. When he felt uneased, he would uncover his face and say in that very state: "May the curse of Allah be upon the Jews and the Christians, for they took the graves of their prophets as places of worship." He wanted to warn against what they did.

Abu Hurayrah (may Allah be pleased with him) reported: The Prophet (may Allah’s peace and blessings be upon him) said: "O Allah, do not make my grave an idol that is worshiped. Allah cursed the people who took the graves of their prophets as places of worship."

Abu Hurayrah (may Allah be pleased with him) reported: The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Do not turn your houses like graves, and do not take my grave a place for celebration, and invoke (Allah's) blessings upon me, for your invoking of Allah's blessings upon me will reach me wherever you may be."

‘Ā’ishah, the Mother of the Believers, (may Allah be pleased with her) reported: ’Umm Salamah mentioned to the Messenger of Allah (may Allah's peace and blessings be upon him) that she had seen a church in Abyssinia called Māriyah, and she mentioned the images that she had seen therein. The Messenger of Allah (may Allah's peace and blessings be upon him) said: "Those are a people who, when a righteous slave or a righteous man from among them dies, they build a place of worship over his grave and place those images therein. Those are the most evil people in the sight of Allah."
