He reported God’s messenger as saying, "Every and when the day of the fast of any of you comes he must not use vile language or raise his voice, and if anyone reviles him or tries to fight with him he should tell him he is fasting.”
*This is not from the Qur’an, but is a hadith qudsi, a tradition which gives words spoken by God.
Abu Huraira reported God's messenger as saying, "He who fasts during Ramadan with faith and seeking his reward from God will have his past sins forgiven; he who prays during the night in Ramadan with faith and seeking his reward from God will have his past sins forgiven; and he who passes Lailat al-qadr in prayer with faith and seeking his reward from God will have his past sins forgiven."
Abu Huraira reported God's messenger as saying, "When the first night of Ramadan comes the devils and the rebellious jinn are chained, the gates of hell are locked and not one of them is opened; the gates of paradise are opened and not one of them is locked, and a crier calls, 'You who desire what is good, come forward, and you who desire evil refrain.' Some are freed from hell by God, and that happens every night."
Tirmidhi and Ibn Majah transmitted it, and Ahmad transmitted it from a man. Tirmidhi said this is a gharib tradition.
Sahl b. Sa'd reported God’s messenger as saying, "In paradise there are eight gates among which is a gate called ar-Rayyan which only those who fast will enter."
