It is narrated from Sayyiduna Abu Basrah Ghifari (may Allah be pleased with him), he says that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When you pass by the Jews, do not greet them with Salam, and if they greet you with Salam, then in reply say only «وعليكم» 'And upon you as well.'"

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that he said: The Messenger of Allah, peace and blessings be upon him, said: "When you meet the polytheists (and according to another narration, the People of the Book), do not initiate the greeting of peace with them, and if you encounter them on a road, force them to the narrowest part of it."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Do not initiate the greeting of salam to the Jews and Christians, and if you meet any of them on the road, force them to the narrowest part of it."

Sayyidah Umaymah bint Ruqayqah (may Allah be pleased with her) says: I came to the Messenger of Allah (peace and blessings of Allah be upon him) with a group of women to pledge allegiance to him. We said: O Messenger of Allah! We pledge allegiance to you that we will not associate anything with Allah, will not steal, will not commit adultery, will not kill our children, will not fabricate slander, and will not disobey you in matters of goodness. The Messenger of Allah (peace and blessings of Allah be upon him) said: "(Alright) but according to your ability and power." We said: Allah and His Messenger are more merciful to us than our own selves. O Messenger of Allah! Now come (and extend your hand) so that we may pledge allegiance. The Messenger of Allah (peace and blessings of Allah be upon him) said: "I do not shake hands with women; my verbal agreement with a hundred women is like my verbal agreement with one woman."

Abu Huraira (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "Every son of Adam inevitably commits a share of adultery; the adultery of the eye is looking, the adultery of the hand is touching, the heart desires and wishes, and the private part either confirms it or denies it."

It is narrated from Sayyiduna Nu’man bin Bashir (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said:“In mutual love, mercy, and compassion for one another, the example of the believers is like that of a single body: when one limb suffers, the whole body responds with wakefulness and fever.”

The Messenger of Allah (peace and blessings be upon him) said: "Whoever causes harm to the Muslims regarding the matter of the road, then their curse will be established upon him."

It is narrated from Sayyiduna Mustawrid (may Allah be pleased with him) that the Noble Prophet (peace and blessings of Allah be upon him) said:“Whoever unjustly eats a morsel belonging to a Muslim, Allah Almighty will feed him from the food of Hell in proportion to it. Whoever unjustly wears a garment belonging to a Muslim, Allah Almighty will clothe him with a garment from Hell in proportion to it. And whoever, by means of (defaming) a Muslim, takes a stand of showing off for fame, Allah Almighty will make him stand in a place of (exposure and) notoriety on the Day of Resurrection.”

Sayyiduna Sa'id bin Zayd (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The greatest injustice is to violate the honor of a (Muslim)."
