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.
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.
عن أبي هريرة رضي الله عنه قال : قال رسول الله صلى الله عليه وسلم :
" أتاكم رمضان شهر مبارك فرض الله عليكم صيامه تفتح فيه أبواب السماء وتغلق فيه أبواب الجحيم وتغل فيه مردة الشياطين لله فيه ليلة خير من ألف شهر من حرم خيرها فقد حرم " . رواه أحمد والنسائي
Abu Huraira reported God’s messenger as saying, “Ramadan, a blessed month, has come to you during which God has made it obligatory for you to fast. In it the gates of heaven are opened, the gates of al-Jahim are locked, and the rebellious devils are chained. In it God has a night which is better than a thousand months. He who is deprived of its good has indeed suffered deprivation."
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."
